Cold Springs Trail (#328): This trail traverses the south slopes of Baldy, crossing several large, sage-covered bowls. It is the route used for the famous “Cheeso Double" event in the Sun Valley Ski Education Foundation Baldy Hill Climb. Riders bike up the mountain before downloading on the ski lift to join the traditional foot-race to the top.
Mountain Biking: Riders have many options for enjoying great trail experiences on Bald Mountain. The Sun Valley Company has been developing and improving its mountain bike trails on the mountain, and the 2015 season will bring new and improved trails to the mix. Pedaling up Baldy can be approached on several trails. The Bald Mountain Trail is the most direct, and is open to uphill bike traffic only. The Warm Springs and Cold Springs trails circumnavigate the mountain, and depending on your pleasure, you can use either as your route to the summit. The River Run and the Warm Springs Traverse trails allow riders and hikers to cross over on the lower flanks of the mountain. Both the Warm Springs and Cold Springs trails are open to downhill mountain bike traffic. The mountain service roads on Bald Mountain are closed to bicycling. The Cold Springs Trail, and the upper reaches of the Warm Springs Trail are closed until July 1 of each year to protect calving elk.
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 hiking and mountain biking, dining at the Roundhouse Restaurant, or simply enjoying the spectacular views from the summit. Uphill hikers generally take the shortest route to the summit via the Bald Mountain Trail. *For more detailed descriptions, topo maps, and information on the history, geology, and wildflowers of the Wood River Valley pick up a copy of Exploring Sun Valley online or find it at one of several local shops.
