Alice Lake (Sawtooth Wilderness)

Alice Lake is an alpine lake in the western United States in central Idaho, located high in the Sawtooth Mountains in the Sawtooth National Recreation Area. In Blaine County, the lake is one of the largest in the Sawtooth Wilderness and is most easily accessed via the trailhead at Pettit Lake, accessed from State Highway 75 via Sawtooth National Forest road 208.

The direct route to the lake begins at the trailhead at the end of the Pettit Lake campground. The trail distance is about 5.5 mi to the lake and gains about 1600 ft in elevation. The trail requires five stream crossings, only the last of which has a bridge.

With a surface elevation of 8602 ft above sea level, Alice Lake can remain frozen into early summer. The lake is framed by the rocky peaks of the Sawtooth Mountains, to the east is El Capitan at 9901 ft.

Alice Lake is within the Sawtooth Wilderness; wilderness permits are obtained at a registration box along the trail at the wilderness boundary, at the upstream end of Pettit Lake.
