Three Sisters Group Site is located within the Lake Como Recreation Area on the Darby Ranger District of the Bitterroot National Forest. The group site, which is located across the road from the Rock Creek Horse Camp, is situated among the pine trees and is adjacent to the outlet of Lake Como.
Boating, fishing, swimming and other water sports are popular on Lake Como. Anglers might see rainbow and cutthroat trout, as well as kokanee salmon, among other alpine species. A boat ramp and parking area are available at the south side of the lake. A large, sandy beach is available to visitors at the North side of the lake. To the West of the site on the North side, a short walk will take visitors to a trailhead that begins a 7-mile loop trail around Lake Como. The Lake Como National Recreation Loop Trail is suitable for hiking, mountain biking and accessing the lake for swimming or picnics. The first quarter-mile of the trail is wheelchair accessible and the trail also crosses Rock Creek at one point. Approximately 3.5 miles from the site, at the West end of the lake, is a magnificent waterfall that cascades over fern-covered rock cliffs. A trail continues from the waterfall, or heads west up Rock Creek, into the Selway-Bitterroot Wilderness area.
Three Sisters Group Site has a 20’x30’ pavilion, equipped with 6 picnic tables, 1 BBQ grill, and 2 serving tables. The site also has benches around a fire ring, two outhouses, and accommodations for 25 vehicles. The maximum number of people allowed at the site is 75. Water, electricity, and firewood are not available at the site .
The group site is located near the East end of 913-acre Lake Como in the central Bitterroot Mountains of western Montana. It is situated at an elevation of 4,245 feet and is primarily used for meetings, reunions, weddings and family gatherings, as it can accommodate a larger group of people. A variety of wildlife and birds can be seen around the area and its surroundings. Osprey, bald eagles, deer, moose, elk and bears make their home in the area (learn about outdoor safety ).
From Darby, Montana, continue north on Highway 93 for 4 miles. Turn west onto County Road 82/Lake Como Road. Follow signs to the Lake Como Recreation Area and continue West past Forest Road 1111 towards the Boat launch, to the site which is on the North side or right hand side of the road.
