Avalanche Lake is a Glacier National Park favorite—and for good reason. This moderate, forested hike serves up waterfalls, alpine views, and a dramatic lake basin framed by steep cliffs and hanging snowfields. The trail is friendly for beginners who want a bit of a challenge without sacrificing scenery, and it’s especially good for families or hikers looking for a half-day adventure.

When to Go
This trail is typically snow-free by late May to early June, making it one of the first big hikes to open each season on the park’s west side. It stays accessible through September.
- June: Waterfalls are raging, wildflowers bloom, crowds are lighter
- July–August: Peak visitation—get there early
- September: Cooler temps, fall color, fewer people
Early mornings offer the best light for photos and a higher chance of solitude.

Nearby Add-Ons
If you’re not ready to head back just yet:
- Kayak Lake McDonald: Rentals available at Apgar—just a short drive west
- McDonald Creek Overlook: Quick photo stop near the trailhead
- John’s Lake Loop: A quieter 2-mile hike nearby with creek views and fewer crowds
- Historic Lake McDonald Lodge: 15 minutes away for snacks, gear, or just a peek at the rustic 1913 architecture
You get alpine payoff without an alpine slog—and maybe even a quiet log to sit on at the lake’s edge. Avalanche Lake is one of those hikes that earns its popularity but still feels personal, especially if you beat the crowd or linger till late afternoon.
