About Warm River Cabin
Overview
Warm River Cabin is located less than 20 miles from Ashton, Idaho, at Warm River Springs. An Idaho fish and game hatchery operated here from the 1930s to the 1950s. The cabin was formerly the hatchery manager's house. It was constructed by the Civilian Conservation Corps (CCC) in 1938. The cabin is open year-round and can be accessed by car in the warmer months. Snowmobiles and cross-country skis are required to access the cabin on a groomed trail from early December through mid-May. The trek from the nearest available parking at Bear Gulch Trailhead to the cabin is 6 miles. Guests should be prepared to bring much of their own gear and supplies to make their stay comfortable.

Hikers, horseback riders and mountain bikers can use the nearby trails. Off-road vehicle enthusiasts, snowmobilers and cross-country skiers can find trails within 10 miles Visitors can find an abundance of berries ripe for picking in late summer.
