Straddling the Montana–Idaho border, Bitterroot National Forest spans 1.6 million acres of dramatic mountain terrain established as protected land in 1898. The forest encompasses both the Bitterroot and Sapphire mountain ranges, with elevations climbing from 2,200 feet along Idaho’s Salmon River to 10,157-foot Trapper Peak—the highest point in the Bitterroot Range and a challenging but rewarding summit for experienced hikers.
Nearly half the forest—743,000 acres—falls within designated wilderness areas, offering backcountry solitude increasingly rare in the American West. Hunters prize these remote reaches for elk, mule deer, black bear, and mountain lion, with both rifle and archery seasons drawing visitors each fall.
The forest maintains 24 campgrounds ranging from rustic to developed. Historic rental cabins like Horse Heaven Cabin and Twogood Cabin provide a unique lodging experience, while Magruder Rangers House offers larger group accommodations. Three Sisters Group Site works well for family reunions or organized outings, and Spring Gulch serves as an accessible base camp for day trips.
Missoula, Montana—located approximately 45 miles north of the forest’s main access points—provides the nearest full-service airport, outfitters, and supplies. Highway 93 runs along the forest’s eastern boundary through the Bitterroot Valley, making most trailheads reachable by passenger vehicle.
Peak visiting season runs June through September when high-elevation trails clear of snow. Fall brings spectacular larch displays and prime hunting conditions, though visitors should prepare for early snowfall above 7,000 feet.
