The route starts near Big Sandy Lake. See the Getting There
section on the main page for directions. This is commonly done as a backpacking trip, although it is possible to day hike this mountain from the Big Sandy Trailhead.
From Big Sandy Lake, hike north on the Jackass Pass Trail. When it's convenient (almost anywhere before the pass), start bushwhacking up the south slopes on grass, talus, and through boulders near the top. To keep it easy, aim for slightly right of the summit until the broad east ridge is reached. This can be followed to the top.
Standard hiking gear for the climb. Backpacking gear for the approach.
