Founded in 1898 and encompassing the Bitterroot and Sapphire Mountains, the Bitterroot National Forest is a federally protected region that is mostly located in western Montana but extends into eastern Idaho.
It is home to three distinct wilderness areas where virtually any development is prohibited, as well as several recreation areas, campgrounds, and trails.
The terrain in the region is predominantly mountainous, but grasslands proliferate lower elevations, many of them leased to private ranchers for stock. But as the hills climb into mountain peaks, the landscape is taken over by several species of evergreen trees, mostly Lodgepole Pine and Douglas Fir.
The forest is home to some of the densest animal populations in the region outside of Yellowstone, including even some great mammals like black bears, mountain goats, white-tailed deer, and even a small grizzly bear community. Though hunting is allowed, seasons are highly regulated by season and limited to only certain species.
This natural landscape lends itself to a myriad of activities, from hiking to horseback riding to Alpine skiing. If you’re at all a fan of the great outdoors, you’re sure to find something to entice you to visit the Bitterroot National Forest.

Main Attractions in Bitterroot National Forest
While visitors frequent most corners of the Bitterroot National Forest, there are some regions and sights within it that attract more visitors than others. If it’s your first time there, you may want to keep some of these popular features and attractions on your radar when planning your excursion.
Carved into the eastern foothills of the Bitterroot Mountains, the glacially carved Bitterroot Canyon begins near the Idaho Montana border, continues through Blodgett Lake and along Blodgett Creek to the Bitterroot Valley.
Outdoor enthusiasts of all types visit the canyon for hiking, fishing, and horseback riding, but climbers in particular frequent the region. There are several excellent opportunities for rock climbing throughout the canyon, but the south face of Flathead Buttress is legendary for its nearly 1200 ft climb.
Partially contained within the Bitterroot National Forest, the Selway-Bitterroot Wilderness straddles the Idaho/Montana border. Dominated by tall granite peaks and surrounded by dense evergreen forests, it’s one of the largest protected wilderness areas in the United States.
The highest peak in the Bitterroot Mountains, Trapper Peak is over 10,000 feet tall. You can climb it via the Trapper Peak trail, an 8-mile climb up its eastern face beginning from Troy Creek Road
Between May and October, the Friends of Darby Historical Center operates a small but mighty museum in the now restored former home of the Darby Ranger Station. The museum also serves as a visitors center where you can find maps, permits, and information about the surrounding wilderness and forests.
In the lobby of the Forest Service office in Hamilton is the Discover Bitterroot Store where you can find educational books, maps, and even stuffed animals of local Montanan fauna. All the proceeds from the store benefit conservation efforts in the area.
Stay Overnight in the Bitterroot National Forest

Magruder Ranger’s House • $100/night
A former ranger station on the Selway River, the Magruder Ranger’s House is a two-story, five-room cabin that sleeps up to six people. The Forest Service provides propane and wood for the stoves and there is running water that services an indoor bathroom with a shower. The road leading directly to the cabin is drivable, so it’s a great option for those who don’t care to hike in.
While the park is open to the public year-round, campground season generally runs from Memorial Day until Labor Day, with some sites open until fall for hunting season. The Forest Service allows dispersed camping as long as you follow the rules they prescribe.

Activities in Bitterroot National Forest
Because of its diverse geological and natural landscape, the Bitterroot National Forest is a prime location for rafting, fishing, hiking, and more. Rather than source all your own gear and plan your own routes, you can hire an experienced, local guide to plan an adventure excursion for you.
Family-owned and operated since it opened in 1938, Lost Trail Ski Area is a Montanan local favorite. They operate within the Bitterroot National Forest via a use permit issued to them by the Forest Service, and its prime location near the Montana/Idaho border on the Continental Divide gives them notoriously great snow.
Bitterroot Adventures is an adventure tourism outfit that specializes in ATVs and snowmobiles. They offer both guided tours and rentals during the winter months.
If you’re looking for a leisurely river float or fly fishing excursion, you can book a guided tour with Bitterroot River Rafting Adventures. They can arrange trips for singles up to larger groups.
Offering hunting and fishing tours, Montana Hunting Fishing Adventures has trips as short as a day up to their week-long comprehensive Fishing Guide School.
Trail Routes in Bitterroot National Forest
The trails of Bitterroot National Forest range in difficulty and length, and although they are technically open to traverse year-round, many of them may become impassible or difficult to navigate in the winter due to snow. At higher elevations, snow can remain well into summer, though they are usually clear by the middle of July.
In total, there are over a hundred designated hiking trails throughout the forest, but here is a selection of some of the forest’s most popular paths.
This nine-mile trail begins near Darby off of Forest Road #5638 and connects to the State Line Trail that runs along the Montana/Idaho border. It’s a popular trail for horseback riding as the trailhead has plenty of parking for trailers.
