Bastion Peak, in the northern Wind River range, stands tenth highest among Wyoming peaks having a prominence of 300 feet or greater. The summit proper is less eye-catching than its craggy northeast buttress (13,470 feet above sea level), which cuts a striking figure from Grasshopper Glacier to the north (Photo 1) and from the upper reaches of Gannett Creek (Photo 2). A formidable, exposed ridge (Photo 3) separates the two summits.

Getting There

The approach to Bastion Peak requires several days' worth of wilderness travel in the northern Wind River Range. The shortest approaches to climbs east of the Continental Divide start from the Green River Lakes, Trail Lake, and Cold Springs trailheads. From the north, Grasshopper Glacier provides an easy approach. From the south, one can ascend Gannett Creek from the Glacier Trail. For information on how to reach Grasshopper Glacier or the Gannett Creek route, see Joe Kelsey’s refreshingly literate guidebook, Climbing and Hiking in the Wind River Mountains.

Red Tape

Bastion Peak is in the Fitzpatrick Wilderness of Shoshone National Forest. Wilderness regulations apply. No permits or fees are required in the wilderness. One of the shortest approaches is from the Cold Springs trailhead on the Wind River Indian Reservation. Getting to Cold Springs requires buying a tribal permit to cross the reservation and hiring an Indian outfitter.


Camp anywhere you can find a flat spot. On summit day you'll probably wake up above timberline, possibly on snow.
