Overview
Avalanche Lake is one of the most popular hiking destinations in Glacier National Park. The trail winds through an ancient cedar forest, opening up to a pristine glacial lake framed by towering cliffs and spectacular cascading waterfalls.
Practical Info
Suggested Duration3-5 hours
Best TimeJune through October is prime, with early June showcasing dozens of spectacular, snowmelt-fed seasonal waterfalls cascading down the sheer 2,000-foot glacial amphitheater cliffs. The ideal hiking window is 7:30 AM to 10:30 AM; early morning rays pierce the mountain basin to cleanly illuminate the emerald-green alpine lake mirror before heavy pedestrian traffic crowds the narrow shoreline trail.
Getting ThereThe epic 4.5-mile round-trip trail originates from the Avalanche Creek picnic area along the western span of Going-to-the-Sun Road. Drive 16 miles from West Glacier straight to the parking loop, which routinely fills by 8:00 AM. Leaving your vehicle at the Apgar Visitor Center and riding the complimentary park shuttle bus directly to the Avalanche Creek transit platform is highly recommended.
Travel Tips
- The 2.3-mile one-way trail encounters regular black bear activity; afternoon return rushes create bottleneck delays at narrow canyon bridges where idling is restricted.
- The lake basin is an active avalanche and rockslide debris cone; picnicking or resting directly beneath the vertical northern cliff walls is hazardous and restricted.
- Visitors without a westbound vehicle reservation can bypass gate limits by boarding the free park shuttle at the Apgar Transit Center before 07:00.
Reviews
Positive
- A high-value alpine lake that lives up to its name! After walking through an ancient cedar rainforest, the lake opens up, framed by waterfalls cascading down sheer glacial cliffs.
- The 2.3-mile one-way trail is well-maintained, mostly compacted dirt or boardwalks with gentle slopes; management is great with wide wooden benches placed along the shores for rest.
- The Avalanche picnic area at the trailhead is fully equipped with clean modern restrooms, sorting trash cans, and water fill stations, sitting right next to the free shuttle stop.
- A perfect wild spot for family day-hikes, picnics, and shooting reflections; user density is low at dawn/dusk, letting you enjoy a secluded, quiet Montana ambiance.
Heads up
- Being the most family-friendly and popular trail in the park, user density severely overloads from 9 AM to 3 PM; the shores are packed with noisy tourists, disrupting the peace.
- Sharing a tiny trailhead lot with Trail of the Cedars, open spots vanish before 8 AM; self-driving guests must wait in long queues on main lanes, making traffic flow sluggish.
- The mid-section gets extremely muddy during spring snowmelts or heavy rain, exposing loose rocks and wet roots; without hiking shoes, climbing steep muddy slopes risks slips.
- Aside from the bulletin board at the start, miles of dense woods lack multilingual safety alerts or cellular signals, creating communication barriers during wildlife emergencies.
