The Desolation Peak Trail is a one-way in-and-out trail that begins at the eastern shore of Ross Lake and ends on the summit of Desolation Peak. There are two trailhead options. Land bound travelers can begin their trail hike from the Lightning Creek Landing (see article this website). Boaters have the option of accessing the trail from the Desolation Boat Dock about two miles closer to the summit. During low lake water levels the dock can be inaccessible; a nearby rocky beach may be an alternative.
