Mount Borah Peak is part of the Lost River Range in the Challis National Forest, the highest mountain in Idaho, looming over the landscape at 12,662 feet. It is a popular destination for mountain climbers and hundreds of hikers who trek on the lower reaches. Scaling the peak is challenging, and proper preparation and equipment are necessary for a safe ascent. A 5,000-foot hike up the mountain from the trailhead lets you log your name in the summit box.
