Hiking the Kolekole Trail to Puʻu Hapapa on Oʻahu, Hawaiʻi

Distance: 3.1 miles / 5.0 km

The Kolekole Trail to Puʻu Hapapa is one of my favorite hikes on Oʻahu!

I have such a bias for Hawaiian dry forest hiking because I think it makes for the best trail running, but I love Puʻu Hapapa because of the climbing, the exposure, and crazy beautiful views, all located in such a short distance!

However, the Kolekole Trail is one of the more unique places to hike on Oʻahu because the barriers to access the trail that prevent most from even attempting the hike.

How to Access the Kolekole Trail?

Since the Kolekole Trail is located on Schofield Barracks, you are required to either be a valid DOD card holder, accompanied by someone who is a valid DOD card holder, or have a visitor pass.

That being said, the visitor pass is, by far, the most tedious and annoying method to access the hike, and being the case, many non-DOD card holders simply avoid the trail altogether because of this barrier.

When is the Kolekole Trail Open?

The Kolekole Trail is open on select weekends only.

To learn more about the trail’s furture schedule, hikers are encouraged to check out the U.S. Army website linked below.

Kolokole Trailhead Parking

Once you’re on Schofield Barracks, the Kolekole Trail is located at the summit of Kolekole Pass on the very back of the base.

Parking for the trail is on the side of the road, or in the little parking lot surrounding the trailhead.

After a number of consecutive closed weekends, the parking area/ trail can be exceptionally busy in the morning. That said, I love hiking Kolekole in the afternoon because of the beautiful evening light.

Hiking the Kolekole Trail to Puʻu Hapapa

The Army only advertises the first 0.3 miles (0.5 km) of the trail to the bench overlooking Lualualei Valley to the west.

However, real hiking begins as you make your way up the ridge to Puʻu Hapapa.

Initially, the trail is very well-marked to the bench.

From here, the Kolekole bench is off to the right, and the start of the Puʻu Hapapa Trail is on the left.

Puʻu Hapapa Trail (Honouliuli Contour Trail)

Know that the short roundtrip distance is a bad indicator for difficulty on Puʻu Hapapa. Hiking to the summit is absolutely beyond some peoples’ ability so use your best judgement.

I watched a couple from the bench spend about 30 minutes scooting only 200 ft. (61 m) down the ridge. When I passed them higher on the mountain, I could hear one of them having difficulty with the much easier flatter sections, but they were not prepared for the high-exposure on the way down.

It’s always easier going up than coming back down.

Puʻu Hapapa Trail (Honouliuli Contour)

The first part of the trail follows the Honoluiuli Contour for the first 0.25 miles (0.4 km) to the first ridge, which is where you’ll have to make a decision about which route to take.

Puʻu Hapapa Loop Trail

This is the first of two ridges that lead up to the summit of Puʻu Hapapa, and the first (west) ridge is also the more difficult of the two.

Personally, I love the high-exposure, the climbing, and the views, but if you have any doubts with your comfortability to heights and exposure, then keep going straight. This first ridge has many areas where you cannot fall! Stay on the Honouliuli Contour Trail until you come to the second ridge leading up to the summit, which is also the ridge I took back down later in this post.

Additionally, for anyone hiking the Waiʻanae Summit Trail (WST), this first ridge is the WST, not the second.

Yes, it’s very steep!

This is the gap in the mountain that you can see from the bench below, and it’s also where the climbing and the exposure start to get real. Many people turn back here.

Like I said earlier, you cannot fall!

These first stretches past the gap are where some of the highest exposure is.

After the both ridges comes together, the rest of the hike to the summit is much more mild.

Waiʻanae Summit Trail (WST)

Do not hike further on the Waiʻanae Summit if you weren’t planning on it.

The Kolekole Trail to Puʻu Hapapa is the easiest section of this stretch to Pālehua, and there are many more difficult sections ahead, including both the Gorilla Heads and Pōhākea Pass.

There are also no great trails off the WST between Puʻu Hapapa and Pālehua because this is the longest stretch on the WST without another trafficked ridge up and down.

Hiking Down Puʻu Hapapa

If you took the first (west) ridge up like I did, look out for the split on the way back down to take the much more gradual east ridge on the Puʻu Hapapa Loop.

It’s always much more difficult going down the west ridge than hiking up.

The bottom of the ridge may not look as obvious as the west ridge, but the Contour Trail will become more defined shortly after making the left turn back toward Kolekole.

I’ve had a friend make this wrong turn when we hiked the entire WST, and he got lost behind a firing range for some time.

Native Plants on the Kolekole Trail

The Kolekole Trail to Puʻu Hapapa is one of the better hikes on Oʻahu to see native Hawaiian plants.

I saw Kōlea, Hōʻawa, Kōpiko, ʻŌhiʻa lehua, Alaheʻe, Kokolau, ʻIlima, and ʻAkoko to truly only name a few. There were so many more that I was surprised to see on just this short hike.

If you would like to learn more about these and many other native Hawaiian plants from across the islands, I encourage you to check out my separate post linked below.
