The tallest mountain in Idaho located outside of the Lost River Range, Diamond Peak rises like a pyramid above the surrounding mountains. The first half of the hike is straightforward on a moderate trail, but once on the ridge the route provides plenty of climbing options for the eager scrambler, though it may overwhelm novice hikers.
