Avalanche Lake

Overview

Avalanche Lake dishes out maximum Glacier drama for a modest hike: a glacially carved amphitheater, sheer cliffs, and multiple waterfalls fanning into a clear blue-green lake. It’s fed by meltwater high above (including from Sperry Glacier), and the whole scene feels like a natural stadium of rock and water.

The Hike (Getting There)

The trail starts at the Avalanche Picnic Area, next to Trail of the Cedars and near Avalanche Campground. It’s about 2.3 miles one way with roughly 500 feet of gain—steady but approachable. Expect a boardwalk/forest start, then a gradual climb through deep, mossy woods to the lakeshore.

What You’ll See

• Avalanche Creek’s narrow gorge and whitewater early on—great photo stop.
• Old-growth western red cedar and hemlock that’s rare in Glacier, cool and shaded in summer.
• The payoff: a glassy lake backdropped by cliffs and a curtain of waterfalls dropping from the cirque. Walk the shore to change up the angles—the far end can reveal even more falls.

Wildlife

Deer and marmots turn up regularly, and both black and grizzly bears are known in the area. Carry bear spray, give wildlife space, and keep all food sealed and attended—this corridor is serious bear country.

Logistics and Amenities

There are no facilities at the lakeshore—plan to pack in/out. All the infrastructure you’ll use is at the Avalanche Creek area: parking, restrooms (some seasonal), potable water, picnic tables, and a campground. In summer, a shuttle stop here can save you the parking headache.

Fishing

Anglers do try their luck at the lake, with deeper water toward the back shoreline. Know current regulations and handle native fish with care.

History & Geology

Named in the 1890s after observers witnessed repeated avalanches in the basin, the lake sits in a classic glacier-carved bowl. Today’s waterfalls trace the same high routes ice once did, feeding the lake from hanging valleys above.

Best Time to Visit

• Time of day: Mornings are best—softer light on the cliffs and far fewer people. Midday gets crowded and harsher for photos.
• Day of week: Weekdays beat weekends.
• Season: Late spring through fall, snow permitting. Early season can mean lingering snow/mud but juicier waterfalls; later summer brings drier tread and warmer lakeside lounging.
• Parking: Arrive early or ride the shuttle during its summer run.

Make the Most of It

• Start early to breeze through the gorge area before it clogs up.
• Keep walking along the shore for different perspectives; don’t stop at the first opening.
• Use the picnic area and restrooms at the trailhead before you head up; there’s nothing at the lake.
• Bear safety isn’t optional here—spray on your hip and clean food habits.
