The Glacier Avalanche Lake Trail in Glacier National Park, Montana, is one of the park's most rewarding short hikes, covering 4.6 miles round trip with just 500 feet of elevation gain. Beginning at the Avalanche Creek Trailhead on the Going-to-the-Sun Road, the route combines a flat, wheelchair-accessible boardwalk through an ancient cedar grove with a forested gorge trail to a cirque lake fed by four cascading waterfalls.
The trailhead is located at the Avalanche Creek pullout on the Going-to-the-Sun Road, approximately 16 miles east of the west entrance near Apgar. During peak season (mid-May through Labor Day), the free Glacier National Park shuttle stops at this location, eliminating the need for a timed vehicle reservation. Those arriving by car must secure a Going-to-the-Sun Road vehicle reservation through recreation.gov. Restrooms are available at the trailhead pullout.
The first mile follows the Trail of the Cedars, a paved and boardwalk loop through an ancient grove of western red cedar and black cottonwood that survived the 2003 Trapper Fire. The canopy creates a lush, mossy environment even in midsummer. Beyond the loop, the Avalanche Lake Trail continues alongside Avalanche Creek through a narrow gorge of polished red argillite rock—one of the most photographed sections of the route—where glacial-blue water churns through sculpted stone channels.
At the lake, four separate waterfalls descend directly from the cliffs of the surrounding cirque, fed by snowfields and the retreating remnant of Sperry Glacier above. The lake is encircled by old-growth forest on its lower shore and sheer rock walls on three sides. The water ranges from deep blue-green to turquoise depending on light conditions. The trail surface alternates between packed gravel, roots, and uneven rock in the upper gorge section. Bear spray is required throughout Glacier National Park. The park entrance fee or America the Beautiful Pass applies; no additional trail permit is needed.

- The gorge section is most dramatic in June and early July when snowmelt keeps water levels high
- Arrive before 9 a.m. on summer weekends to secure parking at the Avalanche Creek pullout

Frequently asked questions
Is the Avalanche Lake Trail suitable for young children?
Yes, the 4.6-mile round trip with 500 feet of elevation gain is one of the most family-appropriate trails in Glacier National Park. The gorge and waterfall setting keeps the route engaging throughout, and most children can manage the full distance.
Is the Trail of the Cedars section wheelchair accessible?
The Trail of the Cedars is a paved and boardwalk loop that is wheelchair accessible. The trail beyond it to Avalanche Lake has rocky, uneven sections and is not suitable for wheelchairs or strollers.
How do visitors reach the trailhead without a vehicle reservation?
The free Glacier National Park shuttle stops at the Avalanche Creek pullout during summer (mid-May through Labor Day), departing from the Apgar Transit Center. Using the shuttle eliminates the need for a timed vehicle reservation on Going-to-the-Sun Road.
What is the best time of year to see the waterfalls at full flow?
The four cirque waterfalls are most powerful from June through mid-July when snowmelt is at its peak. By late August, water volume decreases significantly, though the falls remain visible throughout the hiking season.
Is a permit required to hike to Avalanche Lake?
No trail permit is required for day hiking. A park entrance fee or America the Beautiful Pass is required; the Going-to-the-Sun Road vehicle reservation is needed for those driving but can be avoided by using the free park shuttle.
