This is the most popular hiking route to the top of the mountain. This trail is open to bicyclists traveling uphill from the start on the River Run side to where it intersects with French Connection. Bald Mountain Trail is hiker only from French Connection to the top.
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 wildflowers. Many people branch off onto the many service roads that the trail crosses as it climbs, allowing for a lot of shorter options. Taking the trail to the top of Baldy involves over 3000 feet of climbing, but is still a very popular option for many hardy souls. When the
Mountain bike riders have many options for enjoying great trail experiences on Bald Mountain. The Sun Valley Company has been developing and improving all of its mountain bike trails on the mountain. At the start of the 2018 season they opened two more directional flow trails. Mindbender is a mid-mountain intermediate 3.5-mile freeride trail. Pale Rider is low on the River Run side of the mountain. It's an advanced, black-diamond freeride hybrid that is steep, fast, and technically demanding.
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. One popular route when the lifts are running is to hike approximately 3 miles up Bald Mountain Trail to its intersection with Round House Connector. Then take Roundhouse Connector 0.7 miles to Roundhouse Lodge where you can download on the Gondola.
Bald Mountain now has a much wider variety of trails available for your mountain biking pleasure. Thank you Sun Valley Company, and to all the people working there who have done so much work to make these super improvements happen!
Pedaling up Baldy can be approached on several trails. The beginning of Bald Mountain Trail open to uphill bike traffic only to French Connection, if on a bike, you must continue on to French Connection to the Traverse Trail. Combining the Warm Springs Perimeter Trail #328, and the Cold Springs Perimeter Trail #328, provides for the possible circumnavigation of the mountain, and depending on your pleasure, you can use either as a route to the summit.
(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.
