Fodor's Expert Review Avalanche Lake Trail
Waterton Lakes National Park
Trail
From Avalanche Creek Campground, take this 3-mile trail leading to mountain-ringed Avalanche Lake. The walk is only moderately difficult (it ascends 730 feet), making this one of the park's most accessible backcountry lakes. Crowds fill the parking area and trail during July and August and on sunny weekends in May and June. Moderate.
