Avalanche Lake Trail: A Must-Do Hike in Glacier National Park

The Avalanche Lake Trail is a must-do hike in Glacier National Park and one of the most popular trails on the park’s west side. This moderate 5.9-mile out-and-back trail rewards hikers with a stunning alpine lake framed by towering peaks and cascading waterfalls. With its accessibility, beauty, and family-friendly nature, it’s no surprise Avalanche Lake frequently lands on top 10 lists for best hikes in the park.

Getting to the Trailhead

The trailhead is located off Going-to-the-Sun Road near the Avalanche Creek Picnic Area, on the west side of the park. This is one of the busiest sections of Glacier, especially during peak season, so it’s crucial to arrive early in the morning or later in the afternoon if you want a chance at finding parking.

Starting Out: Trail of the Cedars

Most hikers begin their journey on the Trail of the Cedars, a beautiful, wheelchair-accessible boardwalk loop that winds through a shaded old-growth cedar and hemlock forest. About halfway through the loop, you’ll see a junction with the Avalanche Lake Trail.

The Climb to Avalanche Lake

From the junction, the trail follows Avalanche Creek as it gradually ascends through the forest. The creek is absolutely mesmerizing with its crystal-clear turquoise waters rushing through a narrow gorge. This portion of the hike is scenic and shaded, making it a pleasant uphill journey.

After gaining about 730 feet in elevation, the trail eventually levels out as you approach Avalanche Lake. The lake itself is the highlight of the hike, its tranquil, glassy waters reflect the surrounding cliffs and peaks, where waterfalls cascade dramatically down from the hanging valley above. It’s the kind of spot that invites you to linger for photos, a snack, or just to take in the views.

Retracing Your Steps

Since this is an out-and-back trail, you’ll return the way you came. If you began the hike via the Trail of the Cedars, you’ll complete the loop on your way back to the parking area, offering a final peaceful walk through the towering trees.

When to Hike

The best time to hike Avalanche Lake Trail is from late May into October, when the Going-to-the-Sun Road is open to vehicle traffic. In the winter and early spring months, this area of the park is closed to cars, but adventurous hikers, snowshoers, or skiers can still access the trailhead by traveling the road under their own power.

Additional Notes

• Pets are not allowed on this trail (or most trails in Glacier), so plan accordingly.
• Bear spray is strongly recommended, as Glacier is bear country.
• This hike is family-friendly and great for beginner to intermediate hikers who want big views with a manageable effort.

Final Thoughts

Whether you’re hiking for the views, the waterfalls, or the peaceful lake setting, Avalanche Lake is one of Glacier’s crown jewels. Just be sure to plan your timing wisely to avoid the crowds and fully enjoy the serenity of this incredible spot.
