Leatherman Peak
Leatherman Peak rises to 12,228 feet and is the second-highest mountain in Idaho, located in the rugged Lost River Range. While Borah Peak receives most of the attention, Leatherman offers a quieter and more remote experience with multiple route options to the summit. The mountain can be climbed from either the east or west, with the Northeast Gully now generally considered the standard route. This Leatherman Peak hiking guide covers the mountain’s key stats, route options, difficulty, and what to expect on Idaho’s second-tallest summit.

How Hard is Leatherman Peak?
Leatherman Peak is a serious climb no matter which route is chosen. The standard Northeast Gully route is rated Class 3 and is the safer and more straightforward option for most hikers. The West Ridge is shorter in mileage, but looser, more technical, and better suited for experienced climbers. In both cases, this is a mountain for strong hikers who are comfortable with steep terrain, light scrambling, and route-finding.
Best Time to Hike
Leatherman Peak is generally best climbed in summer and early fall when the gullies and ridges are free of lingering snow. Earlier in the season, snow can add significant difficulty and increase objective hazards on both routes.
Route Options
Northeast Gully
The eastern approach of Idaho’s second-tallest mountain takes hikers deep into the stunning and seldom-visited Pahsimeroi Valley. This route is now generally considered the standard route on Leatherman Peak. It is more difficult to reach by vehicle than the western approach, but it provides a safer line to the summit through a panoramic setting. The trail is well-defined until the gully, where steeper terrain and light scrambling take over near the summit.
West Ridge
Once considered the standard route up the mountain, Leatherman’s western approach is not for the novice hiker. Rotten talus chutes and treacherous cliffs make this route more difficult to navigate and better suited for experienced climbers. Those who choose it will still find a unique approach and a rewarding view from Leatherman Pass.
Should You Hike Leatherman Peak?
If you want Idaho’s second-highest mountain and are comfortable with steep, rugged terrain, Leatherman Peak is a rewarding objective. Most hikers should choose the Northeast Gully, while the West Ridge is better left to those with stronger scrambling skills and a higher tolerance for loose rock and exposure.
