Bald Mountain offers a variety of scenic trails that can be accessed from the base areas at River Run or Warm Springs. Riding chairlifts from River Run (mountain bikes are allowed) to the 9,000-foot summit gives you the option of descending the Bald Mountain Tral on foot, or the Warm Springs or Cold Springs legs of the Perimeter Trails on foot or mountain bike. Both the Warm Springs and Cold Springs Trails will necessitate short rides on the Wood River Trails System bike paths back to River Run.
General Information
Directions: Getting to River Run: Head west on Sun Valley Road through Ketchum. Road curves to the left (south) onto 3rd Avenue. Follow this road down to the river Run Lodge parking lot. Cross the bridge on foot, and look for the trailhead to the right of the river Run chair or purchase a lift ticket inside the lodge.
