Hiking the Koʻolau Summit Trail (KST) North to South on Oʻahu, Hawaiʻi

Distance: 56 miles / 90.1 km

The Koʻolau Summit Trail (KST) is the hardest trail on Oʻahu and across all of Hawaiʻi.

That being said, there are other resources with extensive amounts of information about the KST and its different parts, but there’s not one article that talks about the entire trail, including aspects such as where to find water, things to look for, things that I wish I would have known, or, in my opinion, the most important thing—how to break it up.

I say, how to break it up, because if you’re ever planning to thru-hike it, hike the KST in sections first. Trust me, these mountains will break you down in some way or another. Everyone working toward this goal has had great and bad days on the KST. Whether it be weather, injury, you’re in over your head, or something else, you’ll see what I mean if you start venturing north.

I finished my KST goal on April 21, 2020, and since then, I have spent countless days back on the summit trail, enjoying some of my favorite and less-than-ideal miles.

In any case, not every section has photos, but when I can, I will update this article.

Koʻolau Summit Overview

Starting off, I believe the official distance is 56 miles (90.1 km). It may be more or less depending on how you record it, but if you have a different thought, I’d love to hear why in the comments.

However, if you think 56 miles (90.1 km) doesn’t sound bad because you’ve hiked longer than this on a mainland national forest trail, those who have completed the KST might laugh.

I’m not kidding when I say it will test you! The KST will test your ability to hike far, your ability to climb/ scramble crumbling basalt, your tolerance for mud (and I mean mud pits), your tolerance for overgrowth, and your ability to keep calm while constantly being exposed to drops that would be fatal.

All this tough talk aside, the KST is a cool goal, and I want anyone to be prepared for what they’re getting into because some sections are very remote and unforgiving.

Thru-Hiking the Koʻolau Summit Trail

One of the most important things is to not go into a KST thru-hike blind. This has been attempted many times, and I cannot think of one successful thru-hike that was completed by a person with no prior experience.

For example, you can check out Jackson Grove’s post about when he and some friends decided to go into the hike blind and failed not long after beginning. What he actually didn’t know is that he was very close to the next cabin. But, since he hadn’t been there before, how could he make a safe decision to push forward instead of turning back like they did? They also had no prior experience on the Kalihi Saddle, which was presumably their worst mistake. This aside, Jackson is a good friend, and he is planning on finishing the KST someday!

In any case, before attempting a thru-hike, the KST should have already been hiked in sections, as everything north of the ʻAiea Ridge Trail requires a lot more planning and preparation than everything south of it. However, everything south of ʻAiea begins to get into 'Saddle Territory,' which are the single-most difficult sections of the entire summit trail.

If you are new to the island, I would say that you should have already hiked the majority of the following access trails before beginning long and remote sections on the KST. I can’t tell you how many times knowing exactly what my exit trail options were saved me in crappy situations. Knowing these trails kept others in the group sane when I could be confident on every trail leading up to the KST, in order to get us home safely.

When it’s all said and done, that 56 miles (90.1 km) is going to start to look like 100 (160.9 km), maybe 150 miles (241.4 km) because of the ridges up and down, depending on how you choose to break it up.

I hope it stands out to you how many trails there are in the south compared to the north.

Additionally, I didn’t include every access trail, as someone very knowledgeable might see, but these are the best and most viable options to get you up or down safely.

Hawaiʻi Hiking Pants

Out of all the gear items on the list below, good hiking pants are arguably the most important item, as they are an absolute must on the KST!

The pants below are my recommendations that hold up the best with the overgrowth here in Hawaiʻi, but with any hiking pants that need to be durable, make sure that they are at or near 100% nylon. This is really the most important factor!

North Koʻolau Summit Trailhead Parking

Parking for the KST is located along the side of Pūpūkea Road on the North Shore of Oʻahu. This is the same trailhead as the Kaunala Trail.

If you’re going to be away for more than a day hike, I would advise against leaving your car here for multiple nights, as break-ins have been known to occur at this trailhead.

It must be said before you attempt anything up north, but plan it!

My Koʻolau Mountain Apple Maps

You might think that you are, by reading this, but that’s not what I mean. I mean that personally, I’ve spent countless hours using Apple’s 3D satellite maps, dropping and labeling pins, so that I knew exactly where to go.

The detail is phenomenal on Apple Maps, which is something that Google Maps simply doesn’t compare to. Sorry, but there’s a clear advantage for Apple users on the KST.

This is important because when you’re hiking in the north, having pins will keep you sane when you look around you and feel like you haven’t moved.

Therefore, drop pins for various points on the trail. They should be obvious portions of the trail that you can identify to keep you on track.

Additionally, always mark your trails down and identify the water sources. This picture should give you an idea of how much knowledge is on my phone, and yours should start to look like this too.

Pūpūkea Summit Trail

The start of the Koʻolau Summit Trail begins up Pūpūkea Road past the Boy Scout Camp.

Be aware that no part of the Kaunala Trail is a part of the KST, with the exception of Pūpūkea Road.

From the trailhead, walk up Pūpūkea Road as if you’re going to hike Kaunala. However, when you reach the split for the lower Kaunala Loop at about 0.6 miles (1.0 km), continue further up the road.

The true start of the KST doesn’t begin until after 2.6 miles (4.2 km) of walking up Pūpūkea Road.

After 2.6 miles (4.2 km), the true KST Trailhead splits off Pūpūkea Road at just about the back/ top of the road, which may or may not be marked by a few ribbons.

Pūpūkea Summit Trail

Past the true trailhead, the KST begins on what’s known as the Pūpūkea Summit Trail, but it’s only after Pūpūkea Summit that the 'real' hiking begins.

By this, I mean that the entire stretch from Pūpūkea Summit to Kōloa Cabin is long, overgrown, and feels like you're not making much progress at all. However, the one upside is that you hardly feel the elevation gain because Pūpūkea Road climbs to about 1,450 ft. (442 m) before the trail actually begins.

Pūpūkea Summit is where most hikers that have come this far turn around.

For this reason, I said earlier that the 'real' hiking begins after Pūpūkea Summit, as the trail is obviously less traveled past this clearing.

KST - Pūpūkea Summit to Lāʻie

In my opinion, it’s quite a blessing when the trail gains enough elevation to get out of the invasive Strawberry Guava because it typically means the end of the pig tunnels!

Mālaekahana Ridge is not a trail that you want to rely on to get back down.

Additionally, the KST gets significantly easier after the Mālaekahana junction because the Strawberry Guava will end shortly after.

That being said, Mālaekahana and Lāʻie Summit are not that close, but showing more photos wouldn’t show any more detail or additional information between the two summits.

KST - Pūpūkea Summit to Lāʻie

Lāʻie Summit

It’s almost impossible to say, 'Look for this bush or that tree,' but you need to find the Lāʻie Ridge Trail when you pass it if you’re planning on using it as your exit trail.

This is why I recommend dropping a pin ahead of time, as there may or may not be a sign at this junction.

KST - Lāʻie Summit

Lā’ie Summit on Apple Maps

If you’re looking for Lāʻie Summit on Apple Maps, it will look like this photo on the right.

In any case, after Lāʻie Summit, the KST will come to the marshy meadow in the photo below, which will be 'easier' to find on Apple Maps.

This is also where people tend to take the wrong trail because the state has put up additional fencing that doesn’t follow the KST and seemingly leads nowhere important if you follow it on maps.

Mark this area well, and when you pop out of the bushes at the meadow, look to the right directly across and up the little hill. The photo below is of the same meadow but looking north (back).

Furthermore, the trail across the meadow is where the KST continues, and from here, you can’t get too turned around for the rest of the hike to Kōloa Cabin.

The meadow that you need to cross looking north. The trail is on the far side on those two hills.

Soon after the meadow, the KST meets with the fence in the photo below, where it goes straight or left if you’re facing south.

Don’t follow the fence to the left, as it leads nowhere, but continue following the more obvious path along the fence.

KST - Lāʻie to Kōloa

When you come to this steep hill in the photo below, you’re getting close to Kōloa Cabin.

You’ll probably see the outhouse first, and then you’ll come to an area to hop the fence right next to the cabin.

KST - Lāʻie to Kōloa

Kōloa Cabin

For a long time, Kōloa Cabin was locked, but as you can see, someone broke in, as they usually do. I won’t give my opinions on this, but I’m just glad that the cabin is still accessible.

That being said, don’t leave trash in the cabin. If you stay in it overnight, try to clean it so it can continue to be open for the next hikers.

Furthermore, Kōloa Cabin is a water source from a rain catchment, but be sure to purify the water before drinking.

If you only planned for one night on the KST, then your best option is turning around to Lāʻie Summit, which is roughly 1-1.5 hours of hiking back north.

However, if you planned for a longer hike south, continue on to the next section.

All said, my friend and I started at around 9 a.m. from Pūpūkea, which I considered to be a late start. I wanted to start at seven, but we had to make a few last-second stops.

The whole trip there took about 9.5 hours to get to Kōloa due to some bad weather and all the overgrowth, but if you cut the KST short at Lāʻie Ridge, know that the trail gets significantly easier once you reach the junction for Lāʻie Falls.

This 9.5 hours was done with gear to sleep in the cabin, but day hiking from Pūpūkea to Lāʻie Summit only is more practical, in my opinion.

KST - Kōloa Cabin

Nope, it’s Not Locked!

Kōloa Cabin to ʻŌpaeʻula Cabin

If you’re breaking the KST up like I recommend, then hike back up Lāʻie Ridge to Kōloa Cabin in order to continue south.

If you choose to hike up Lāʻie Ridge to ʻŌpaeʻula and down Papali, the hike will be about 17.5 miles (28.2 km) total.

Kōloa Cabin to ʻŌpaeʻula Cabin

From Kōloa Cabin, the KST wraps around the backside as if you hadn’t walked down to it.

Then, the KST continues along the fence as normal, but quickly you lose the fence and enter some of the worst overgrowth on the entire summit trail. It took my friend and I about three hours, moving at a decent pace with large backpacks, to push through this section the first time I hiked it.

KST - ʻŌpaeʻula Cabin

However, when I returned some years later, I was able to move at a very fast pace through this same section with only a day pack, and it only took 1.5 hours to hike from Kōloa to Papali Summit!

That’s an incredibly fast pace, and I wouldn’t plan for this if it’s your first time. There may be some strategy to not camping anything up north, but only do this if you can hike all of the sections light and fast before the sun sets.

In any case, this section alone is why marking the trail on your phone ahead of time will keep you sane.

When you’re mapping it, you will lose the trail at parts and regain it later because it’s almost a joke to call the KST 'a trail' at some points.

Then, when you finally break through the overgrowth, you’ve arrived at the Papali Summit, which is the photo below.

Papali Summit is a big horseshoe in the fence line, and from here, it’s truly an easy walk compared to what you just went through to get to ʻŌpaeʻula Cabin.

Furthermore, be aware that ʻŌpaeʻula Cabin is slightly off the KST, following a different fence that meets the KST fence from the west. Mark this junction, so as not to miss it.

ʻŌpaeʻula Cabin

Personally, ʻŌpaeʻula is my favorite cabin on the island, but again, please leave it cleaner than you found it, so that it can continue to be used by future hikers.

What happened to ʻŌhikilolo Cabin in the Waiʻanaes would be a shame if it happened on the KST too.

All said, ʻŌpaeʻula Cabin is another reliable water source from rain catchment.

Papali Ridge Trail

The Papali Ridge Trail is a pretty straightforward hike, and it eventually meets with the Maʻakua Ridge Trail for the last mile and a half before ending in Hauʻula.

However, when you come to a brown sign for the Kaluanui Forest Reserve about a third of the way down Papali, look for the trail on the left!

It’s not very obvious, and it seems like you should continue following the fence, but I promise it leads nowhere! I’ve followed it by mistake, and it was pretty heartbreaking to turn around at the end of it.

KST - Papali Summit

ʻŌpaeʻula to Poamoho

If you choose to hike down Papali Ridge, then you have a few options in order to complete this section.

First, you could retrace your steps up Papali to meet the ʻŌpaeʻula junction and continue south to Poamoho. Alternatively, you could hike north from Poamoho to ʻŌpaeʻula as an out-and-back trail.

In either case, I highly suggest hiking Poamoho at some point, as it is one of the best access trails across the entire Koʻolau Mountains.

Poamoho Permits

If you choose to camp in ʻŌpaeʻula Cabin from Poamoho, you’re going to need two permits to avoid any legal trouble with the Department of Land and Natural Resources (DLNR).

This means two different people have to get a Poamoho permit for different days, as they won’t issue two permits to the same or different people if they see you’re in the same group and trying to camp.

These two permits are mostly for the dash of your car, which could be one for a Saturday and one for the following Sunday.

KST - Boot Junction

ʻŌpaeʻula to Poamoho

From the ʻŌpaeʻula junction heading south, the KST is more of the same: lots of overgrowth and lots of mud.

In my opinion, this part of the trail feels very monotonous because you are constantly looking at Punaluʻu Valley for seemingly 75% of the way, and it barely feels like you’re making any progress when you look out.

Castle Falls

Eventually, the KST passes over a little stream called Castle Stream (Castle Falls), which may or may not be a reliable source of water.

This is also where the views of Punaluʻu Valley begin and continue for the entire hike to Poamoho.

Boot Junction

Shortly past Castle Stream, the KST crosses a large meadow, where the trail makes a hard left turn, commonly known as the 'Boot Junction,' on the south side of the meadow. This is where you’ll need to hop the fence to continue along a different fence after crossing the meadow, prior to reaching the boot.

On Apple Maps, this meadow is one of the more obvious places to mark near Punaluʻu Valley. However, since there’s a fence along this entire section, ʻŌpaeʻula to Poamoho may be the easiest section on the NKST to find in Apple Maps.

All said, I personally enjoyed starting and ending at Poamoho the first time I did it because the elevation gain is not nearly as bad compared to hiking up Papali Ridge.

KST - Poamoho Summit

Poamoho to Mānana: The Middle KST

[This Section is Written from South to North: Mānana to Poamoho]

Poamoho to Mānana, or rather Mānana to Poamoho, is typically most hikers' final KST section, as these are some of the most challenging miles to access.

To add to this, Schofield-Waikāne is generally not a good access trail to break up this section because the summit is just too close to Poamoho to make it worth it. By this, I mean that the section between Schofield-Waikāne and Poamoho is known commonly as the 'Highway Miles,' being that they are some of the fastest and easiest miles on the entire KST.

Therefore, it simply doesn’t make sense to hike the 7-mile (11.3 km) Schofield-Waikāne Trail when the section between Schofield-Waikāne and Poamoho is so easy comparatively.

Why Do I Recommend Day Hiking from South to North?

I recommend hiking south to north (Mānana to Poamoho) for one main reason: difficulty.

By this, I mean that the further you hike north of Mānana, the better the trail gets. Rather, if you go in reverse (north to south), you’ll start out on an excellent trail and hike into harder and harder miles, finishing on the rollercoaster trail that is Mānana Ridge.

Poamoho to Mānana

Additionally, from Mānana to Kīpapa, the KST rides a rollercoaster of a ridgeline, and it isn’t until after Kīpapa that you hit the KST contour trail. That’s the difference between the KST vs. KSRT (Koʻolau Summit Ridge Trail), which you may have read about in other blogs.

With whatever you decide, the reason I recommend a long day-hike over camping in this section is that I found that carrying camping gear only makes the hiking slower and harder. However, carrying only what I needed made a huge difference in terms of success on this section.

All said, the total distance from the Mānana Trailhead to the Poamoho Trailhead is 18.6 miles (29.9 km) but in my case, I couldn’t coordinate a pickup from the Poamoho trailhead, so it was actually 24.5 miles (39.4 km) to the Poamoho gate!

Mānana to Poamoho

To hike this section in one day, which is what I recommend, start Mānana Ridge well before the sun comes up, so that you ideally finish before the sun goes down.

On this day, I started at 2:30 a.m. at the Mānana Trailhead, and looking back, I wouldn’t have done it differently because starting this early got me to Poamoho gate an hour and a half before sunset!

In any case, I began the 5.8-mile (9.3 km) Mānana Ridge Trail at 2:30 a.m. and arrived at the summit at 5:10 a.m.

KST - Mānana Summit Looking South

From Mānana Summit, turn left (north) on the KST toward Waiāhole Valley.

The next summit you will reach is the Mānana Corner (Waiawa Summit). It is the high point on this section, and it was a little while after I started to traverse Waiāhole that the sun started to come up, the first time I ever hiked it.

The middle of Waiāhole is the Waiawa Gap.

Essentially, the Waiawa Gap is a low point, like a mini overgrown 'saddle,' where you will lose roughly 700 ft. (213 m) of elevation from the Mānana Corner; then, you have to regain nearly all of it to climb out of the gap to Waiāhole Middle, the first summit on the north side of the valley.

Waiāhole Middle

Waiāhole Middle may seem a little obscure, but you’ll know you’re on Waiāhole Middle when you’re standing on the peak where the north ridge of Waiāhole Valley meets the KST from the east side.

For some adventurous hikers, this ridge has actually been used as an access trail, but I personally couldn’t speak to it.

In any case, Waiāhole Middle is about a half-hour or less away from Kīpapa Summit.

KST - Waiāhole Middle

Kīpapa Summit

During my initial KST hike, I reached Kīpapa Summit at 8:50 a.m., which is what gave me so much hope that I was doing well on time.

It’s also here that you will visibly see the contour trail directly ahead.

In any case, the Kīpapa Ridge Trail can be used to bail off the KST for whatever reason, but I would never recommend it or recommend turning back toward Mānana.

I say this because I believe Kīpapa should be the dividing line between Poamoho and Schofield-Waikāne in terms of your safest and closest trails down.

All said, there is a cabin exactly 2 miles (3.2 km) down Kīpapa, but the hike is terribly overgrown, which is why I would never advise heading down that way.

Read My Separate Post: Kīpapa Ridge Trail

Kīpapa Summit

Leeward Contour

Leaving Kīpapa, you’ll drop in elevation immediately into an oddly-placed Sugi Pine grove before popping out on the contour trail.

From a distance, the trail looks distinct, obvious, and clear, but much of it is thigh to waist-high Uluhe overgrowth until the Windward Notch.

Nevertheless, this section is called the Leeward Contour because at no point do you want to follow the ridgeline. Rather, the contour, which winds like crazy while hugging the mountain and seems to drag on forever, is definitely easier to follow than the ridge.

The KSRT Heading North from Kīpapa

Windward Notch

Eventually, after your second fence crossing, also called 'selfie junction,' you’ll see the Windward Notch off in the distance.

This notch is an obvious cut-out hole in the mountain where the much easier trail begins to take over.

If you are planning this on Apple Maps, which I cannot recommend more highly, you’ll notice two distinct trails cut into the side of the mountain joining together right below the notch. The upper is the KST, and the lower leads down to Waikāne.

The Windward Notch is also the signifier that the hardest hiking is behind you!

However, I don’t recommend taking a break at the notch because the much clearer Schofield-Waikāne Summit is shortly ahead, and it’s a much better place to eat some food.

Schofield-Waikāne Summit

On the long day that I hiked from Mānana to Poamoho, I arrived at Schofield-Waikāne around 1:00 p.m., and from there on, the distance started to fly by.

I say this because even though it may look significant compared to what you’ve already done, the rest of the hike to Poamoho is significantly easier than everything leading up to this point; hence, why I prefer to hike south to north.

The 'Highway Miles'

The stretch in between Schofield-Waikāne and Poamoho is what I like to call the 'Highway Miles'.

I say this because outside of the very beginning and end of the KST, no section of the summit trail moves as fast as this stretch between Schofield-Waikāne and Poamoho.

KST - Schofield-Waikāne to Poamoho

KST - Schofield-Waikāne to Poamoho

In my experience, whenever the KST regains the fence line, the hiking generally gets easier, and whenever it loses it again, the hiking generally gets a little slower.

Poamoho Cabin

In my experience, Schofield-Waikāne to Poamoho Cabin generally takes between 1.5-2 hours.

The trail is clear, you’ll follow the fence line most of it, and you’ll be at Poamoho in no time!

Additionally, the Poamoho Cabin is another reliable water source, which is important to note because from this section all the way to the Moanalua Saddle, finding water can be unreliable.

If you choose to hike in the same direction, the remaining hike is an easy 3.5 miles (5.6 km) down the graded Poamoho Trail.

Ideally, you will have planned a pick-up from, but if you’re like me, you may have to walk.

I actually jogged the extra 5.9 miles (9.5 km) out of there, so that I wasn’t walking the long access road in the dark.

All in all, I finished at the Poamoho Trailhead at about 4 p.m., which was a pretty great feeling, as this was my last section on the Koʻolau Summit Trail!

Mānana to ʻAiea

[This Section is Written from North to South: Mānana to ʻAiea]

For this section and the remainder of the article, the KST is written from north to south.

In any case, I’ve personally hiked Mānana to ʻAiea in both directions. I don’t believe there is one best way to do it, but whatever you decide, this is another section where I recommend a long day hike, as opposed to camping.

In my opinion, hiking with a big bag only makes this section unnecessarily more difficult.

Mānana to ʻAiea

From Mānana Summit, there is a short traverse to get across to ʻEleao, which will take roughly 15-20 minutes.

ʻEleao Meadow

ʻEleao, also called ʻEleao Meadow, is a grassy meadow at the corner of Waiheʻe Valley.

That being said, I would never consider ʻEleao to be a good campsite because the meadow acts like a wind funnel—right where you would want to set up your tent. Even if it’s not windy when you get there, it may still hit you in the middle of the night.

By comparison, Waimalu Meadows across Waiheʻe Valley is a much better campsite, and there are places to get out of the wind.

Leaving ʻEleao, the KST drops off the steep peak as it makes its way down to Waimano.

Waimano is the true low point of Waiheʻe Valley, so for obvious reasons, it’s easy to tell where the summit/ trail is going to be from far away.

From Waimano Summit heading south, the KST climbs back up toward Waimalu; hence, why Waimano is the low point, much like the Waiawa Gap.

Waimalu Meadows

As mentioned previously, Waimalu Meadows is a great place to camp, and you may find water to filter in random areas throughout the meadow. However to be safe, don’t count on any reliable water sources until the Moanalua Saddle.

Nevertheless, the KST moves from Waimalu across ʻĀhuimanu, with ʻAiea Summit shortly after.

In all, doing either one big hike from Mānana to ʻAiea or breaking it up into two smaller hikes with Waimano in between are really the only two ways to consider this section.

KST - ʻAiea Summit Looking North

ʻAiea to Kulanaʻahane: The South KST

In my opinion, everything south of ʻAiea/ Hālawa gets a little more fun, and the trail doesn’t feel like it needs to be broken up as strictly as I suggest for the sections above.

Therefore, go with the weather, do a lot of it in day hikes, and go further or shorter than what I suggest because you have so many more options going up and down the ridges compared to the north.

From ʻAiea Summit, the KST traverses about four major peaks until you descend the fourth, where Stairway to Hell and the Moanalua Valley begin.

On a side note, I wrote a specific article on Stairway to Hell, which does make a fun overnight trip, beginning from the ʻAiea Loop Trail.

Stairway to Hell on Oahu Hawaii

My Print - Stairway to Hell

As the KST moves south from Stairway to Hell, the trail begins to head into 'Saddle territory', which will begin to get tricky.

Therefore, I don’t recommend hiking with a big backpacking bag on any of the saddles, and this is one of the reasons why I’ve steered away from thru-hiking the summit trail.

Moanalua Saddle

Warning

I hope it’s obvious from these photos, but this and every saddle are sections that you do not want to go into unprepared.

All three—which include Moanalua, Kalihi, and Nuʻuanu—are easily the most dangerous sections of the entire KST, which is obviously why completing the entire summit is such an elusive goal.

For this reason, I recommend considering a hike like the Keaʻau Middle Ridge prior to hiking any saddle just to know what 'easy' exposure in Hawaiʻi looks like before attempting something more involved, like any of the saddles.

Kulanaʻahane Summit (The Moanalua Saddle)

The Kulanaʻahane Trail is a good KST access trail, but if you have the daylight, I recommend pushing further to Moanalua Middle, as it would be a much better starting point for the long and tedious Kalihi Saddle immediately following.

Read My Separate Post: Kulanaʻahane Trail

KST - Kulanaʻahane Summit

Kulanaʻahane Trail

For thru-hikers, the Moanalua Stream just below the Kulanaʻahane Summit is a good, reliable water source that’s only 0.25 miles (0.4 km) and less than 300 ft. (91.4 m) of elevation change away from the KST.

KST - Kulanaʻahane Ridge Trail Down to the Moanalua Stream

Kulanaʻahane to Moanalua Middle

The south side of the Moanalua Saddle is more of the same, except there are two sketchy sections, both of which are not very high above Kulanaʻahane.

By sketchy, I mean that the ridgeline climbs very loose dirt/ basalt next to drops that would almost certainly be fatal, so don’t take it lightly. Falls have occurred here before.

Additionally, if it wasn’t clear from the north side of Moanalua, this is also where you need to start hiking with your own ropes.

It’s always best practice to never rely on a rope you didn’t place, especially because KST ropes get replaced far less frequently than others, such as those on Mt. Olomana. I have a bad story about this when I get to the Kalihi Saddle.

That being said, you’ll have to rely on the grass, little trees, and whatever ropes you have to get to Stairway.

KST - Moanalua Saddle

Past the two sketchy sections, which should be contoured to the right on both, the ridge gets significantly 'easier' to reach the summit.

Stairway to Heaven (Haʻikū Stairs)

The south side of the Moanalua Saddle is Stairway to Heaven.

For obvious reasons, the KST in this section will be one of the most trafficked sections across the Koʻolaus, but that only lasts for a short 10-minute walk until Moanalua Middle.

If you choose to hike from Kulanaʻahane to Moanalua Middle instead of continuing on to the Powerline Trail, this might be one of the few times you start and end at your car—no Uber and no coordinating with friends, which only happens here and one other place on the KST.

Read My Separate Post: Moanalua Middle Ridge Trail

KST - Moanalua Middle Summit

Moanalua Middle Ridge

Should you choose to hike Moanalua Middle, please do what you can to minimize your impact, as the ridge is in such obviously bad shape.

Moanalua Middle Ridge

Moanalua Middle to Power Lines

Moanalua Middle to Power Lines is one of the top two most dangerous sections on the Koʻolau Summit Trail.

For that matter, the other side of Power Lines, continuing on the Kalihi Saddle, is the other most dangerous section, and a near-fatal fall occurred as recently as 2023.

Moanalua Middle to Bowman

That being said, the Koʻolau Summit from Moanalua Middle to Bowman is nothing too noteworthy.

The ridgeline traverses a handful of rolling peaks, which seem to move rather quickly because there are a few notable landmarks, like the Bowman Tower shown below.

Then, after a relatively short hike from Moanalua Middle, the KST reaches Tripler Summit, which is the last 'descent' access trail to reach this area of the Koʻolaus before the Kalihi Saddle.

I say 'descent' because Bowman is not a great or practical trail to use.

Read My Separate Post: Tripler Ridge Trail

KST - Kahoʻomoe ʻihikapulani (Tripler Summit)

Tripler to Power Lines (Kalihi Saddle)

Back when I said I’ve enjoyed countless days back on the summit trail, well, the Kalihi Saddle isn’t one of them.

To that point, I’m not sure if I ever have the desire to go back up there just for the sake of filling in this section with photos.

I hope this shows that this one section is not meant for all hikers, even if you have done the majority of the sections surrounding Kalihi, as it’s truly the crux of the route.

That being said, the one benefit that you have from coming from Tripler is that you can place your own ropes. However, I could easily see this section being done in reverse.

Facing Kailua/ Kāneʻohe on the ridge, the left side of the saddle (north side) is much 'easier' than the right (south side).

Be that as it may, don’t read this and think that the north side is now easy. It’s not.

In any case, when heading down to Power Lines from Bowman, you will pass over one big feature called the “Witch's Hat,” which is immediately followed by the Power Line Trail.

On a side note, when I was coming down the saddle this way, I stopped to say something to my friend when suddenly, the ground I was standing on just gave out! The only thing that saved my life was the rope in my left hand. This isn’t meant to scare anyone but to keep you aware of how real and dangerous hiking on this saddle is, as shown by the 2023 hiker who took a 100 ft. (30.5 m) fall.

Power Line Trail

The Powerline Trail is likely unfamiliar to most Hawaiʻi hikers, as most don’t choose to hike the Kalihi Saddle for fun.

In short, Power Lines is a quick, short-distance, reliable trail that leads from the ventilation building for the Wilson Tunnels, right off the Likelike Highway, to the saddle.

There’s no parking here, so you will either have to coordinate with a friend or do a weird Uber pickup/ drop-off. I’ve done Uber two out of the three times I’ve been on the saddle, and it’s always worked for me.

KST - Kalihi Saddle

Power Lines to Lanihuli

If you have completed the north side of the saddle shown in the photo above, know that it’s maybe only 20% of it, and it’s the 'easy' half. The south side is where the hiking gets real!

In the last section, when I said you cross over one feature called the “Witches Hat,” know that you traverse many more of these features going south of Power Lines, and in my opinion, they’re worse!

In order from the Power Line Summit, they go: the “Sharks Fin,” the “Bunny Ears,” the “Doorstop,” the “Pimple,” and the “Can Opener/ Lanihuli Wall.” Each one is challenging in its own way, but I’d say the Lanihuli Wall and the Doorstop are the worst. The Doorstop is the prominent feature in the photo below, with the Bunny ears behind that and the Pimple being the closest.

Furthermore, going down the backside of the Doorstop is sketchy, and this is one of those sections where it would be smart to tie and leave your own rope. Even the traverse to the right of the Pimple is awkward and very dangerous.

In all, making it from Power Line Summit to the base of the Lanihuli Wall has never taken me anything short of three hours. Keep in mind, if you get stuck at the wall, like I did on my first attempt, it’s now three hours back before you can head down, and you don’t want to be up there in the dark!

Additionally, the base of the wall is really the only place to take a short break and eat some food on the majority of the saddle because you are otherwise constantly focused on making every step count.

I’m not kidding when I say if you trip wrong or slip wrong, that could be it.

KST - The “Pimple,” “Doorstop,” and “Bunny Ears” from closest to furthest.

Lanihuli Wall

For a first-time Kalihi Saddle hiker, I would never recommend going from Lanihuli to Power Lines because I believe going up something that vertical is easier than going down.

In any case, at the base of the wall, the trail contours to the left. My first mistake, which is what made me turn around on my first attempt, was thinking we needed to climb directly up the ridge. DON’T! You might get yourself in a bad situation like we did. The KST contours to the left on a less-than-ideal path, while clinging to the Uki grass for dear life.

The Can Opener/ Lanihuli Wall goes like this: Contour left, go up a near-vertical section, contour left again, and go up one more much longer near-vertical section. The ground is soft and sinks in, so tread lightly!

I personally believe that every group makes this trail significantly harder for the next because of the erosion, especially when there’s already so little places to put your weight on as is.

Kalihi Saddle Rope Story

Back when I was talking about the Moanalua Saddle, and I said I had a story about the Kalihi Saddle ropes, well, this is it.

I was climbing the first vertical section using the rope as a guide but heavily relying on the terrain to support my weight.

When I got to the top, I thought I would replace the rope to send down a new one, so there would be something more reliable for the next person. When I started digging into the grass to find out where the original rope was tied that I had in my hand, I found this dead stick no bigger than my pointer finger, and I snapped it in the process of digging.

I was absolutely pissed that some hiker before me thought that the twig was a decent place to trust someone else’s life with. I then redid the rope on the one only reliable thick branch in the area, but even then, I’d say it wasn’t much to trust.

That’s why you should never trust someone else’s work because if I slipped or fell, I was grabbing a rope tied to a dead stick, and I likely would have fallen hundreds of feet down the pali.

KST - Kalihi Saddle

Puʻu Lanihuli (Kapālama Ridge)

Past the Lanihuli Wall, the difficulty doesn’t let up yet, but it does get significantly 'easier' and moves a little faster than the saddle below.

Then, once on the first summit, you go down and up a couple of dips to reach the Kapālama Ridge Trail, located right in the middle of Puʻu Lanihuli.

Personally, I don’t recommend hiking both Kalihi and the north side of Nuʻuanu in one long day. I say this because the Nuʻuanu Saddle has gotten significantly more challenging and more dangerous over the years, due to sections that have and will continue to fall out.

What I’m really trying to say is that some parts of Nuʻuanu are really just like an extension of the Kalihi Saddle, and I think it’s best to rehike the 3.8-mile (6.1 km) Kapālama Ridge Trail in order to come back when you’re better rested.

Read My Separate Post: Kapālama Ridge Trail

KST - Kapālama Ridge Summit

From the Kapālama Ridge Summit, the KST traverses across a few dips before arriving at the south summit of Puʻu Lanihuli, also called 'True Lanihuli'.

After the short traverse from the Kapālama Ridge Summit, Puʻu Lanihuli tops out at the true summit, standing at 2,780 ft. (847 m) above both Kalihi to the north and Nuʻuanu to the south.

KST - Puʻu Lanihuli

Nuʻuanu Saddle

I don’t believe it matters too much whether you choose to hike from Puʻu Lanihuli to the Pali Lookout or in reverse. However, I personally prefer hiking down it than up, as I like to place my own ropes, which is much more feasible when descending.

In any case, I’ve hiked this section in both very rainy weather and on a perfect day, but I only recommend this section when the weather is about as perfect as you can ask for because of how dangerous it really is.

KST - Nuʻuanu Saddle

KST - Nuʻuanu Saddle

Another reason why I prefer to descend Lanihuli on the Nuʻuanu Saddle instead of climbing up from the Pali Lookout is because of the section below.

The 'flatter' part of the ridge before it turns to the left, which you can see in the photo below, is called 'Annie’s Saddle,' and it’s easily the most challenging and dangerous section of the entire route.

For this reason, you can decide rather quickly if turning back is your best and safest option, as opposed to hiking up from the bottom, which would be much more tedious to backtrack.

KST - Nuʻuanu Saddle

KST - Nuʻuanu Saddle

'Annie’s Saddle'

This section at the beginning of Annie’s Saddle is one that I can honestly not remember from my first hike prior to taking these photos.

What this tells me is that over the years it fell out, and will likely continue to do so, meaning that these photos may not be the most accurate representation as the years go on.

What this also tells me is that ropes that had been previously placed will most likely not be safe to use as time goes on. For example, the white rope in the photo below was tied to an ʻŌhiʻa tree where the base fell out from beneath, and the same could be said about our orange rope as time goes on.

KST - 'Annie’s Saddle' (Nuʻuanu)

KST - 'Annie’s Saddle' (Nuʻuanu)

In any case, this descent was the trickiest part of Annie’s Saddle.

We first tried climbing below it to ascend, which proved fatal, as everything I stepped on just kept crumbling under my weight. Then, we tried a side traverse about halfway up, but it also proved too dangerous. So, in the end, we decided that going straight over the ridge was our best bet, as we tried not to knock out too much as we climbed down.

This section took about 4-5 minutes for each of us once we finally figured it out.

KST - Looking Back

After the landslide, there are still a few more features to traverse—some of which need to be climbed over, and some of which should be contoured around.

Eventually, when the KST meets the top of the Nuʻuanu Wall, the end of the Pali Puka Trail below, the trail cuts off the ridge to the right, where it descends a few hundred feet through the forest.

This descent will eventually end when it cuts over to the famous Puka.

KST - Nuʻuanu Wall Contour

Pali Puka

Once down the majority of the north side of Nuʻuanu, the KST meets with the popular Pali Puka Trail, making it the easiest section of this entire stretch to follow down to the parking lot.

Where the Pali Puka Trail ends, continue across to the far side, where the Pali Notches Trail begins.

If you are thru-hiking the KST, know that camping off the Old Pali Highway may be the best place to spend the night.

Additionally, about 1 mile (1.6 km) down the Old Pali Highway is a large rain catchment should you need water.

This will likely be the second-to-last reliable water source before Makapuʻu, with the last being the third waterfall at Kaʻau Crater.

The top of the first notch, shown in the photo below, is where most hikers turn around.

That being said, the first notch is the easiest; the second notch is a bit more difficult to find the hand and feet placement, and the Chimney is the most difficult part of the entire Pali Notches Trail.

KST - Pali Notches Trail

KST - The Second Notch

KST - Below the Chimney

The Chimney

Once at the Chimney, the route climbs up the leeward side. There’s no way for me to put in writing regarding where to put your hands and feet, but I also believe you should have done this climb a few times prior to the full ascent, or you might have to turn around here.

It’s not a bad climb, but the Chimney is more vertical than the Lanihuli Wall.

Also, unlike the Lanihuli Wall to the summit, the Chimney to the summit will not let up, like the saddle does on the south side of Kalihi.

What I mean is that the section gets slightly more difficult above the Chimney, and it’s deceiving how long and, in some spots, sketchy the rest of the hike is to the summit of K1, even more so when the summit looks so close on a clear day!

KST - The Chimney

KST - The Chimney

The Chimney to Puʻu Kōnāhuanui

Past the chimney, there’s a number of exposed sections that you will have to maneuver, usually moving around to the leeward side.

There’s also one chute that resembles a mini waterfall—if there was water—and if it wasn’t for this one tree in the right spot, I’m not sure getting up it would be doable for most people.

In any case, the KST climbs straight to the summit once past this chute.

KST - Looking Down from Kōnāhuanui

Puʻu Kōnānuanui (K1)

Once at the summit of K1, be sure to go left, not right, to continue on the KST to K2 and the ridge trail down to Tantalus.

The trail to the right is for Lulumahu Ridge, which I would regard as a less-than-ideal access trail, considering that the Puʻu Kōnāhuanui Ridge Trail is so much easier.

KST - K1 to K2

KST - Looking Across Mānoa Valley from K2

Puʻu Kōnānuanui II (K2)

As mentioned above, the reason why I stopped this section at K2 instead of K1 is because the trail down to Tantalus from K2 is much better than Lulumahu Ridge from K1.

It almost seems pointless to not do the little traverse between the two peaks.

KST - K2

K2 to Waʻahila (Mānoa Valley)

In no particular direction, Mānoa Valley could be hiked either way with no significant differences in difficulty.

Personally, I traversed Mānoa twice—once toward K2 and once toward Waʻahila—both times using Mānoa Middle to reach the KST.

However, there’s no reason why it couldn’t be done in one day or further because south of K2 is where you begin to have all of your choices to move as far as you want, with any number of ridges to take up and down.

Puʻu Kōnānuanui II (K2) to Mānoa Middle

From K2, the KST moves south across Mānoa.

The KST traverses a lot of downhill sections to Mānoa Middle, as you come off the highest point in the Koʻolaus at 3,150 ft. (960 m) on K1.

KST - Mānoa

On Apple Maps and even in person, it looks like there’s a nice contour trail across the Mānoa Valley, but don’t follow it.

Staying on the ridgeline is much easier in terms of overgrowth until you hit Waiakeakua Ridge, which isn’t until you’re almost at Waʻahila.

KST - Mānoa

KST - Mānoa

Mānoa Middle Summit

Once at Mānoa Middle, assuming you’re on the summit and not the contour trail, stay to the left to keep hiking toward Waʻahila.

It isn’t until shortly after the boulder section seen in the photo below that the KST meets Waiakeakua and the good contour trail across Mānoa.

Then, from Waiakeakua, the KST is a fairly smooth hike until the much easier Waʻahila Ridge Trail to Mt. Olympus.

From Mt. Olympus (ʻAwaʻawaloa), heading south, the KST drops significantly off the peak toward the popular Kaʻau Crater Trail.

This short section between the two day hikes will get slightly more overgrown, but both trails are commonly combined as one longer hike, making this section move fairly fast.

This is the steep descent off Mt. Olympus.

Therefore, the section across Kaʻau is fairly easy compared to all the other sections mentioned previously.

Once past Kaʻau Summit (Puʻu Palikea), the KST begins heading toward Mauʻumae Ridge (Puʻu Kainawaʻanui), sometimes called false Lanipō, followed by true Lanipō shortly after.

KST - Waʻahila to Kuliʻouʻou

Puʻu Kainawaʻaunui (False Lanipō)

This summit in the photo below is Puʻu Kainawaʻanui, better known as the Mauʻumae Ridge Trail summit.

Furthermore, the Mauʻumae Ridge Trail would make for a good access trail to hike back up, but the KST would get even easier by continuing one more to Wiliwilinui.

Read My Separate Post: Mauʻumae Ridge Trail

KST - Puʻu Kainawaʻanui (False Lanipō)

From Puʻu Kainawaʻanui, the KST moves south to the true Lanipō Summit, followed by one more short traverse to get to the popular Wiliwilinui Ridge Trail.

Personally, when I did this section for the first time, I hiked from Waʻahila to Puʻu ʻO Kona, starting at about 1:30 p.m., and I finished just after sunset at the Puʻu ʻO Kona Trailhead.

It’s roughly 8.0 miles (12.9 km) to do it all in one hike, but in my experience, the KST moves very fast when you start recognizing each of the popular summits going south.

South KST Things to Consider

If you plan on doing a long hike like I just described, don’t park inside the Waʻahila State Recreation Area. Rather, park on Ruth Place because your car will get locked in the gate if you return after sunset.

Residential neighborhood restrictions is also something to consider for Hawaiʻi Loa Ridge and Wiliwilinui, as the neighborhood security will not let hikers back up to either trail within a certain timeframe of sunset, granted that you don’t live in the neighborhoods. They might tow your car too. I’m not really sure.

However, it’s a wealthy community, so I wouldn’t put it past them. Therefore, either get dropped off or hike past both summits like I did because I didn’t want to deal with the hassle of their community rules.

The one loophole around this is to reserve a DLNR overnight permit.

To get one, book using the link below, which should provide a sound legal reason to leave a car overnight, whether they know you’re camping or not.

False Puʻu ʻO Kona

Most hikers think that the summit of the Puʻu ʻO Kona Ridge Trail, where the trail down to Kuliʻouʻou Valley is located, is Puʻu ʻO Kona. However, true ʻO Kona is situated between both Kuliʻouʻou Summit and here.

Nevertheless, the Puʻu ʻO Kona Ridge Trail is a great trail to finish on because the popular Kuliʻouʻou-Puʻu ʻO Kona Loop, described below, makes for a great day hike on its own!

Like Poamoho further north, the Kuliʻouʻou Ridge Trail should be utilized when hiking up to the KST, as it’s such an easy-access trail to continue in either direction.

KST - Kuliʻouʻou Summit

Kuliʻouʻou to Kamehame (Dead Man’s)

This section could be broken up with Pyramid Rock to make it two shorter hikes, but I personally think Kuliʻouʻou to Dead Man’s is a great day hike, being that the trail moves so fast compared to most of the sections further north.

In addition to this, Hahaʻione Summit is too close to Kuliʻouʻou to make it feel like you’ve made any progress, and Mariners Ridge should be avoided at all costs if you know that situation.

Finally, Kamiloʻiki is too close to Dead Man’s to stop there, making Pyramid Rock the only reasonable hike in the middle if you wanted to shorten this roughly 7-mile (11.3 km) section.

Kuliʻouʻou to Pyramid Rock

From Kuliʻouʻou Summit and south is where you’ll stop seeing Uluhe ferns on the trail.

You’ll greatly come to appreciate this if you’ve done any of the more overgrown sections prior to hiking in the south.

In any case, Kuliʻouʻou to Hahaʻione is all fairly straightforward.

This is where the KST leaves Kuliʻouʻou Summit to the south.

Hahaʻione Summit

After just 0.4 miles (0.6 km) from Kuliʻouʻou, the KST reaches Hahaʻione Summit, which is the north side of the Pyramid Rock Loop Trail and Hahaʻione Valley.

For the most part, this section of the summit is fairly straightforward, with the exception of a few tricky turns right before Pyramid Rock.

Depending on the amount of maintenance, if any, the trail receives, the grass can be particularly overgrown near the power lines.

At this unique Ironwood tree, the tricky turns on the KST begin and continue until Pyramid Rock shortly ahead.

That being said, go around this tree on the left-hand side, and look for the trail that makes a sharp left turn off the ridge almost immediately after.

It will appear as if this isn’t the correct route at first, but if you don’t make this left and remain on the ridge, the ridgeline will cliff out, and you’ll be looking at Pyramid Rock, instead of being near Pyramid Rock.

KST - Go Left

Just past the tree in the photo above, make a hard left where you wouldn’t expect it, or you’ll end up on the wrong ridge looking at Pyramid Rock instead of standing on the KST next to Pyramid Rock, like I have done a few times.

The left turn is shown in the photo on the left.

The photos below show the hidden left turn that may be tricky to notice.

Following the section above, the KST will continue to descend until it comes to this very vague overgrown area in the photo below.

To continue toward Pyramid Rock, you need to go right on the not-so-obvious trail down this hillside, which will likely look less straightforward than staying on the ridge on the left.

The intersection in the photo below is where the Pyramid Rock Loop leaves the Koʻolau Summit Trail.

The trail to the left around the windward side is the route to continue along the KST, and the trail to the right is the best and easiest path to continue up to Pyramid Rock.

The section from Kamiloʻiki to Dead Man’s is more or less one big down and up, with most of the route finding being fairly self-explanatory.

On a different note, Kamiloʻiki Summit is one of the best places in the southern Koʻolaus to spend the night if you are looking for a place to set up.

As the KST reaches the low point between both peaks, look for the trail that descends off to the right of the ridgeline through the grass.

If not, the actual ridgeline will cliff out, in which case you’ll have to backtrack to find where it drops to the right.

Dead Man’s to Makapuʻu (Tom Tom Trail)

Personally, I prefer to hike this section from the Tom Tom Trail to Dead Man’s, but it could be hiked in either direction if driving the majority of elevation up Kamehame Ridge matters most to you.

Makapuʻu Lookout

It must be said that the KST is NOT the paved Makapuʻu Lighthouse Trail, but rather, the final hill from the Makapuʻu Lookout to make it official.

Personally, I think it would be cheating to come this far and not take the final hill in order to finish the KST.

KST Notes

I don’t think there is anyone I know who has hiked the KST in sections in sequential order from north to south or south to north, like I outlined.

My last section, other than tagging the lighthouse, was from Mānana to Poamoho, which seems to be a lot of people’s final section.

KST Oahu Hawaii

PAU!

In any case, the KST can be tricky because of remoteness, planning, people’s schedules, permits, scheduling pick-ups/ drop-offs, and most importantly, the WEATHER! So many times the weather dictated what section I would hike or avoid.

I’ve had the best days and the crappiest days on the KST. I’ve been poured on while in the north, the Kalihi Saddle, leaving Stairway to Hell, and coming down Lanihuli to the Lookout, and that doesn’t even mention that the Kalihi Saddle took me three separate hikes to complete!

I also barely mentioned all of my long nights in the dark or crazy early mornings to either get down safely or to go after a section early.

Overall, I know everyone will have a different experience, but it's for this reason that I said in the beginning: This trail will test you. Believe me, it will!

I’ve had very confident, capable friends who tried to do it all in one go without first hiking it in sections to which they did well, but on account of the crappy weather they were dealt and their low morale because they didn’t know what was coming next, they only made it as far as Triple Ridge from the north. My friends even used this post to prepare, but this post only does so much compared to seeing the trail for yourself.

All said, I am happy to be the first all-in-one post for the entire Koʻolau Summit Trail!

KST - Dead Man’s

The Koʻolau Summit Trail Record!

As it stands, the current record is 2 days, 7 hours, and 27 minutes, set by Conrad Newfield.

I don’t know the specifics regarding whether it was set completely unassisted and alone, but still, that’s a record that will stand for some time!

The 'Official' KST Thru-hike Rules

Here is the blog written about Chase Norton; the first person to ever set out to connect and complete the entire Koʻolau Summit in one push.

That being said, he had a few general rules/ guidelines over two attempts to keep it fair across the board. Keep in mind that he did many practice hikes to learn the trail before attempting the whole thing in one go.

  1. Carry all your food and camping gear on your back—no stashing gear ahead of you, and no having someone meet you on the KST to resupply you. This includes water. To resupply, you need to use the resources on the trail, like rain catchments or streams.

  2. No bailing off at any point on the trail to sleep a night at home, like the Pali Lookout, and regaining the trail the next day. The push needs to be continuous and uninterrupted.

  3. Hike it alone. This one is a little more loose than the first two because he did have people meet him for some sections, but for the most part, he was alone. Also, hiking it alone takes away the temptation to have friends resupply you.

Native Plants on the Koʻolau Summit Trail

There’s honestly too many different native plants that I could list from my observations on the summit trail, but I really wanted to include this section to say that you will be hiking by some of the world’s rarest plants!

I purposefully excluded location information about some of these species throughout the post, so as not to advise searching for them or disturbing their habitat. Regardless, please do your part to minimize your impact.

If you would like to learn more about identifying native Hawaiian plants from the Koʻolau Summit Trail and around Hawaiʻi, I encourage you to check out my separate post.
