Description / Access Information
Cold Springs Trail #328: This trail traverses the south slopes of Baldy, crossing several large, sage-covered bowls. Climbing on the trail is very demanding near the bottom of the trail where it climbs very aggressively up through the lower reaches of the Cold Springs drainage. Once you make it up to the base of the #4 Cold Springs Chairlift the alignment becomes much more manageable. Here, the route is a rolling contour trail that climbs at grade suitable for intermediate strength riders. After a while the trail breaks out of the trees to cross a number of huge sagebrush and grass covered bowls. If its sunny and hot out this section can be a scorcher.

This trail can be used to descend off of the mountain to the Cold Springs side of the area. Where it is out in the open the route is quite straight and direct. Much of the route is over firm surfaces, but some sections of the trail contain quite a lot of loose angular rock that can throw bike tires around a bit. As is useful on any descent, watch for others who may be approaching from around blind corners. 

The Cold Springs Trail is the more southerly portion of the Bald Mountain Perimeter Trail #328. The other side of the Perimeter Trail is made up of the Warm Springs Trail leg. The Cold Springs Trail is used for “Cheeso Double" portion of the Sun Valley Ski Education Foundation Baldy Hill Climb. This aspect of the famous SVSEF suffer-fest sees riders mountain biking up the Cold Springs Trail to the top of Baldy, then the racers download on the ski lift to join the traditional foot-race back up 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. Sun Valley has recently opened a couple of downhill only mountain bike flow trails to the mix on Baldy. The Saddle Up Trail can be accessed at the top of the mountain. Lupine Trail is accessed off of the Broadway Trail.

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. Both the Warm Springs and Cold Springs trails are open to downhill mountain bike traffic. People can use the River Run Trail and the Traverse Trail to cross the lower flanks of the mountain. 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. The Bald Mountain Trail is open to foot travel and uphill mountain bike traffic.
