Overview

About This Trail

Avalanche Peak Trailhead is a strenuous out-and-back climb around 4.5 miles with roughly 2,100 ft of gain. The surface is packed dirt and rocky scree, with upper slopes that are loose and exposed. The trail is dry for most of the route, and above treeline you’ll face sun and wind with limited shade. Start early to beat the crowds, but be ready for a physical test and a big summit payoff.
