Adventure Description

Adventure Description

Pratt Mountain offers great views of surrounding lakes and peaks. Along the trail there are views of Pratt Lake, Island Lake, Olallie Lake, and Chair Peak's south face.

The hike starts out at the same trailhead as Granite Mountain, but it splits 1 mile in. As the trail for Granite Mountain goes to the right, the moderate ascent for Pratt Lake goes to the left. The trail ascends at a moderate grade for another 3.5 miles, where its splits right for Pratt Lake and Talapus to the left. After the turn right to Pratt Lake, the trail steepens. Steep slopes here present potential avalanche danger.

Around 4.8 miles in, the trail splits again, this time for Pratt Lake and Island Lake. Follow the the sign left to Island Lake. The trail gets hard to navigate here, especially in the snow. Continue along the tree covered ridgeline. Arrive at a clearing around 5.5 miles in. Beyond and above is a steep scramble in the summer or mountaineering in the winter. At this point, an ice axe would be needed during the winter.

The summit of Pratt Mountain is just another 0.5 miles away. There are also views of views of Island Lake, Granite Mountain Lookout, and Chair Peak along the way.
