Located at mile marker 135. 3 on US Highway 12 along the Wild and Scenic Lochsa River, Eagle Mountain Trailhead features a distinctive wooden trail bridge and provides access to over 4 miles of trails into the Selway-Bitterroot Wilderness.

The trailhead offers hitch rails and parking for hikers, backpackers, and horseback riders, with year-round access (though winter road conditions may limit access).

No fees or permits are required, though wilderness regulations apply including group size limits and no motorized vehicles.
