From Darby, MT, follow MT 473 south for 4 miles to West Fork Bitterroot River Rd. A mile past the Job Corps, at milepost 7, turn right on FS 5634 (Baker Point Rd.). Follow this road 10 miles to the trailhead at about 7000 ft.

The trail begins on a FS trail to Baker Lake. There are fish in Baker Lake and there are ample places to fish from the shore of the lake. There are two possible routes from Baker Lake. The first is taking the climbers trail past Middle Lake to Gem Lake. From Gem Lake, there is a gully of slabs and talus that will lead you to the plateau. From the plateau, cut up to the ridge and follow the ridge to the summit using the climbers trail.

The second route follows a different climbers trail due south of the lake that climbs straight up the ridge for 400 vertical ft. From the ridge, follow the ridge west northwest to the peak. Either route can be used to descend from Trapper Peak.

Gem Lake, Middle Lake, and Baker Lake offer potential to camp at the lakes. Be sure to obey local fire regulations as there is limited timber around the lake and fire restrictions around the lakes are instituted on the regular.
