(Note: The Perimeter Trail #328 does not open to the top of the mountain until July 1 to protect calving elk.) Both the Warm Springs and Cold Springs trails are open to two-way bicycle traffic and other allowed shared uses.
The trails on Baldy are non-motorized and therefore closed to electric mountain bike use. The mountain service roads that are not part of Baldy's trail network are closed to bike traffic.
Hikers have a great many options on Baldy Mountain, with the Bald Mountain Trail being perhaps the most popular hiking route on the hill. It's a direct route that starts out along the Big Wood River, out of the Sun Valley Resort's River Run Base Area. The trail climbs through the woods to the base of the Frenchmen's lift area before entering an area of sunshine, grasses, and, in the springtime, wildflowers. Many hikers branch off onto the French Connection Cat-track Trail, or the Roundhouse Connector Trail, to make for a shorter outing. Others climb the Bald Mountain Trail to the top of Baldy. That involves over 3000 feet of climbing, but it is still a very popular option for many hardy souls.
In the summer the Sun Valley Resort runs the Roundhouse Gondola and the Christmas chairlift to the top of Bald Mountain. This provides easy access to downhill mountain biking, dining at the Roundhouse Restaurant, or simply enjoying the spectacular views from the summit.
