Best Hikes in Glacier National Park: Iceberg Lake Trail

Glacier National Park is more beautiful in person than I ever could have imagined. I don’t believe there’s a single trail that’s anything less than breathtaking. So, honestly, when choosing your hikes, you can’t go wrong if you’re looking for a good view.

Iceberg Lake Trail is a great option for hikers of any experience level and is one of the best hikes in Glacier National Park. The trail has a very gradual incline, sweeping views of the valley and surrounding Lewis Range, waterfalls, and wildflowers lining the trail in the warmer months.

Iceberg Lake Trail Highlights

The first half mile of the trail is the steepest section. Once you’re past this, the trail is reasonably flat so don’t let the first section discourage you. From there, the trail follows the ridge to Iceberg Lake which is nestled between Mt Wilbur and Iceberg Peak.

One of the best hikes in Glacier National Park, the Iceberg Lake Trail, follows a ridgeline for sweeping views of the valley and surrounding mountains.
Much of the Iceberg Lake Trail is relatively flat after an initial ascent.

During my visit in late July, the trail was lined with bear grass, wildflowers and huckleberries that were just beginning to bloom. The early morning glow on the wildflowers was gorgeous.

About halfway to Iceberg Lake (approx. 2.5 miles) is Ptarmigan Creek and Falls, which is a perfect rest stop. Keep an eye out for wildlife around here. One woman told us she saw a moose hiding behind a tree along the trail nearby! We had this area to ourselves on the way out, but by the time we returned it was quite busy.

As you make the final approach to Iceberg Lake, you’ll cross a bridge over a small stream. From there, you’ll make your way down a paved walkway towards the lake.

I almost didn’t even notice the lake in front of me because the reflection from the mountain was so clear! As you get closer, the icy blue icebergs floating in the glassy water reveal themselves.

If you’re really daring, go for a dip in the water! There were some people taking the plunge, but it was a bit too cold for me. I put my hands in instead, mostly to make sure this wasn’t all a dream.

Iceberg Lake Trail Tips

The trail can be snow-covered even into June. Before heading out on the trail, check on the trail conditions at one of the visitor centers. I have no doubt the views will be just as beautiful throughout the year, though you will want to take additional precautions in snowy conditions.

Pro Tip: I strongly recommend hitting the trail early (by 8am), if possible. Due to it’s popularity, the trail can become crowded by mid-day. Also, you’ll likely get a nice view of the early morning fog that sits low in the valley.

Most of the trail is exposed to sunlight. Even if you leave early, be sure to bring plenty of sunscreen, water, a hat, sunglasses and food. As always, pack out any garbage and leave no trace.

Pro Tip: One of the unexpected perks of this trail is the pit toilet at the lake. Before going right on the path towards the lake, go left for the pit toilet. I was pleasantly surprised by how clean it was and that there was toilet paper available. Regardless, I recommend bringing your own just in case it’s not stocked.

Iceberg Lake Trail Safety

Why is the Iceberg Lake Trail one of the best hikes in Glacier National Park? It's diversity, from hemlock forest to alpine meadows!

While I highly recommend this hike to anyone visiting Glacier National Park, be aware that the trail is frequented by both black and grizzly bears. In fact, just a few days after I left the park, the trail was shutdown due to bear activity. Don’t let this scare you away from hiking on the trail, just take the appropriate precautions.

For my full list of bear safety tips, read my how to survive hiking in bear country post!

First, don’t surprise the bears. Talk loudly, clap, sing or make whooping noises throughout the hike, especially when you approach blind corners. Second, be sure to have bear spray with you and easily accessible. Before departing on trail, make sure you know how to use the spray! Third, heed the warnings signs and trail closures. The rangers don’t post these unless there is a legitimate risk.

Along the lake itself, there are rocks that make the perfect place to enjoy lunch or a snack. Beware the ground squirrels and other animals that will aggressively try to get your food. They are not shy! Although they’re very cute, please resist the urge to feed them.

Weather changes rapidly in Glacier National Park. Even if it’s bright and sunny when you leave the campsite, I strongly recommend that you bring a rain jacket and small dry bag to protect your electronics. Luckily, I didn’t get stuck in the rail on the trail. However, at the campsite, I saw how quickly the sunshine can give way to a downpour. 

Is the Iceberg Lake Trail One of the Best Hikes in Glacier National Park?

With over 700 miles of trails in Glacier National Park, it’s hard to say. However, as an avid hiker, I found this trail to be very enjoyable and one that I would hike again. If you’re a beginning hiker or prefer to avoid steep inclines but still want to experience the diverse landscapes and wildlife of Glacier National Park, this is a great option. If you’re a more advanced hiker, this trail offers the unique up close view of the icebergs and a more relaxed (i.e. easier on the legs) experience.

My opinion: Iceberg Lake Trail IS one of the best hikes in Glacier National Park.

    Honestly, there were hardly any bugs! I wore some bug spray and that seemed to do the trick. I would say the squirrels and chipmunks were more annoying than the bugs 😉
