Leatherman Peak Loop from Sawmill Gulch Road

This route is considered very strenuous and challenging. It involves significant elevation gain, with approximately 1,295 meters (4,249 feet) over about 12.4 kilometers (7.7 miles) for a typical summit attempt. Expect sections of steep, loose scree and talus, particularly above the cirque. The upper mountain features rugged Class 3 terrain, which includes scrambling and can involve exposure. Route-finding is essential, especially where trails are faint or non-existent.

The initial section often follows a creek through a wooded area before opening into a large clearing. From there, the terrain transitions to steep slopes of scree and talus, especially as you approach the cirque and the ridge. The upper mountain involves rugged Class 3 scrambling over loose rock, which can be reminiscent of the Canadian Rockies. The landscape is raw and beautiful, with pristine creeks and towering mountain sides.

The route typically starts from a trailhead accessible via Sawmill Gulch Road (FS-411). To reach the trailhead, a high-clearance vehicle, possibly 4x4, is strongly recommended due to the rough nature of the road. This can save you a few kilometers of hiking on the road itself.

From the large clearing, you'll gain views of Leatherman Pass, Leatherman Peak, and White Cap Peak. The summit of Leatherman Peak, Idaho's second-highest, offers panoramic views of Borah Peak, Mount Idaho, White Cap Peak, Bad Rock, and the vast expanse of the Lost River Range. Pass Lake is also visible from the summit ridge.

The best time to hike this challenging route is generally during the summer months, typically from late June through September, when the snow has melted and weather conditions are most stable. An early start is recommended due to the strenuous nature and potential exposure of the hike.

While specific regulations for dogs on this particular route are not detailed, trails within the Salmon-Challis National Forest generally allow dogs. However, given the route's extreme difficulty, including steep scree, talus, and Class 3 scrambling, it may not be suitable for all dogs. Always ensure your dog is on a leash and you pack out all waste.

As this route is located within the Salmon-Challis National Forest, there are typically no entrance fees or permits required for day hiking. However, it's always wise to check the official U.S. Forest Service website for the Salmon-Challis National Forest for any current alerts or specific regulations before your trip.

When hiking in the Salmon-Challis National Forest, it's important to practice Leave No Trace principles.

Yes, a portion of this route follows the Leatherman Peak Trail, which covers about 14% of the overall journey. Hikers often utilize the path towards Leatherman Pass and the West Ridge to access the summit.

Given the strenuous nature, significant elevation gain, and rugged terrain, you should bring plenty of water, high-energy snacks, sturdy hiking boots with good ankle support, and layers of clothing suitable for varying mountain weather. A helmet is advisable for the Class 3 scrambling sections, and trekking poles can be very helpful on the scree and talus. Navigation tools (map, compass, GPS) are crucial due to potential route-finding challenges.
