Hiking the Highline Trail (The Loop) in Glacier National Park

Distance (One Way): 13.3 miles / 21.4 km

The Highline Trail is one of the best day hikes in Glacier National Park!

That being said, many people hike this longer trail using a variety of different approaches. However, in my opinion, the best way to hike the Highline Trail is to complete 'The Loop', including the optional ascent up to the Grinnell Glacier Overlook.

The distance above includes the additional 1.6 miles (2.6 km) up to the overlook and back.

Highline Trail

What is the Highline Trail Loop?

The first decision to make is whether to treat the Highline Trail as an out-and-back hike or a one-way trail, hence 'The Loop'.

What 'The Loop' really refers to is a one-way hike from the Logan Pass Visitor Center to The Loop Trailhead (where you would then take the Glacier Shuttle back up Going-to-the-Sun Road, where you parked at Logan Pass).

This is a relatively new option in Glacier National Park because of the implementation of the Glacier shuttle, but in my opinion, it’s the best strategy rather than treating the Highline Trail as an out-and-back hike. An out-and-back hike is a much more difficult choice than simply hiking the longer one-way distance.

I say this because the majority of the Highline Trail, from Logan Pass to The Loop Trailhead, is all downhill, with only a few notable uphill sections, which I’ll highlight more below.

What is the Best Time of Day to Start the Highline Trail?

The answer to this question is easily 'early morning,' but how early is the true question.

You need to arrive at Logan Pass well before sunrise to find parking, which I’ll talk more about below, but when to actually begin the trail is what’s up for debate.

Some hikers prefer to start shortly after arriving, but I personally recommend against this strategy. I say this because the best of the Highline Trail is all before Haystack Butte, so if you start hiking shortly after arriving, you’re going to miss the most scenic views on the trail by starting in the dark.

However, by waiting an hour or two, you are inevitably going to be spending more time in the sun, which is why many groups prefer to start before sunrise. That being said, the Highline Trail is very well shaded in the morning hours because of the mountains that parallel the trail, but as the day goes on, you will start to see how little shade there really is on the entire hike.

This is why I recommend starting early, but not too early. For this to work best, hiking with a hooded sun shirt is essential because trying to continually reapply sunscreen as you’re sweating is not the best strategy, and nearly every hiker that ended at the The Loop Trailhead was sunburned in one way or another. For me, it was my face, but my hat and sun shirt did most of the work that sunscreen could not.

Highline Trailhead Parking

Logan Pass is the most difficult area of Glacier National Park to find parking.

On every nice day during the busy summer season, you can expect the Logan Pass Visitor Center parking lot to fill with cars completely by 7:05-7:10 a.m. I’ve watched it happen more than once.

This means that by 7:20 a.m. cars are already circling the parking lot trying to find a spot, which won’t open up until the first hikers return from the Hidden Lake Overlook.

This also means that if you want to hike either the Hidden Lake or Highline Trail from Logan Pass, you need to arrive by 6:30 a.m. or earlier to be safe, which means factoring in the long drive up Going-to-the-Sun Road from the west entrance. The east entrance to Logan Pass is a bit of a shorter drive.

Overall, having a Glacier vehicle reservation does not mean much if you’re plan is to hike from Logan Pass because of how popular/ competitive it is to find parking.

Hiking Checklist - Glacier

Here is a complete list of must-have things that you will want for any hike in Glacier National Park.

Hiking the Highline Trail

The Highline Trail begins directly across the road from the Logan Pass Visitor Center, and for the first mile, the hike is all downhill until the trail begins approaching Haystack Butte.

Highline Trailhead

Almost immediately after starting the hike, the trail was surrounded with bighorn sheep on either side.

If you encounter them, give them space because they have been known to charge at people.

There are many high-exposure sections throughout the trail where you cannot fall; or it would almost certainly mean death, and I say this for two reasons.

First, the Highline Trail (The Loop) is absolutely not a kid-friendly hike because of the long distance, the sun exposure, and the high cliff exposure throughout the hike. However, perhaps more importantly, the Highline Trail is most dangerous for all people when there is yet lingering snow throughout the park, which will stick around longer at these higher elevations.

This risk is exacerbated when it’s melting during the day and freezing again at night.

Additional Early Season Gear

This is all to say that depending on the winter snowpack, micro-spikes may be necessary throughout the Highline Trail, especially on these more exposed sections of the hike.

I personally use the Yaktrax below.

As the trail nears Haystack Butte, you’ll start to see the two main switchbacks that make up the majority of the uphill to hike around the infamous peak.

Haystack Butte

Outside of the optional Grinnell Glacier Overlook, the elevation gain up Haystack Butte is the most significant on the entire Highline Trail.

For some, Haystack Butte is the turnaround point on the Highline Trail, but I highly recommend pushing forward because majority of the remaining hike is downhill to reach the Granite Park Chalet and The Loop Trailhead.

Haystack Butte

That being said, the uphill doesn’t end at Haystack Butte, but it continues for another 0.6 miles (1.0 km) until the downhill starts to take over.

This obviously excludes the optional Grinnell Glacier Overlook.

Highline-Grinnell Glacier Overlook Junction

At about 6.8 miles (10.9 km) into the hike, the Highline Trail arrives at the junction that leads up to the Grinnell Glacier Overlook.

When most people see the elevation gain required to reach the overlook, they sigh, then start the ascent anyway because of how much it took to make it this far.

I was no different, but on a hot, bluebird August afternoon, this ascent in the direct afternoon sun was anything but easy.

The ascent to the Grinnell Glacier Overlook may only be 0.8 miles (1.3 km) each way, but it’s the elevation gains that’s truly notable.

The Grinnell Glacier Overlook is a pretty amazing experience to be able to see one of the best hikes out Many Glacier from this unique perspective.

Additionally, if you are visiting Many Glacier, I couldn’t recommend hiking to Grinnell any more highly. It’s easily one of the best hikes in all of Glacier!

Once back on the Highline Trail, the Granite Park Chalet is only another 0.8 miles (1.3 km) away.

Highline-Granite Park Junction

Leaving the trail to visit the Granite Park Chalet was not only a cool and unique experience, but it was also one of the best ways to have some time out of the sun.

However, from this junction, there is still 4 miles (6.4 km) left to hike in order to reach Going-to-the-Sun Road, so if you’re pushing your time for the last shuttle, you need to hurry down these last four miles in order to secure a ride back up to Logan Pass.

Up to this point, the Granite Park Chalet has the only restrooms on the Highline Trail since leaving Logan Pass.

Inside the chalet you can find a place to relax, enjoy photos of the park, get the weather, and talk with not only other hikers but employees who stay at the chalet throughout much of the summer season.

I would expect these prices to continually rise, as everything has to travel up the same Granite Park Trail off Going-to-the-Sun Road that is shown below.

If you think you may want to purchase anything like sunscreen or a Gatorade, make sure to bring cash!

It’s pretty cool to look back from the chalet and see where you’ve come from.

From the intersection shown above, 'The Loop' leaves the Highline Trail to begin the Granite Park Trail down to Going-to-the-Sun Road.

The first split in the trail on the way to The Loop Trailhead is for the Granite Park Campground, which is only a short distance after leaving the chalet.

When the trail makes the hard switchback to the west, this began what felt like a never ending switchback!

However, when it finally makes one more turn toward the road, it’s a good mental checkpoint that you’re nearing the end.

Go right down the road, and The Loop Shuttle Stop will be located shortly ahead.

The Loop Shuttle

Since hiking the Highline Trail as a 'Loop' is a popular option, it’s likely that you’ll arrive at the shuttle stop at the same time in the late afternoon/ evening as a number of other hikers.

However, since hikers treat the Highline Trail as a one-way hike, the trail never feels crowded because you’re not passing very many people, as you would on an out-and-back hike.
