Custom Guided Climbs of Gannett Peak and the Dinwoody Cirque

Gannett Peak as approached from the Dinwoody Glacier

Wyoming Mountain Guides offers custom guided climbs of Gannett Peak, the majestic crest of the Wind River Range and highest peak in the state of Wyoming (13,810’), as well as neighboring peaks in the Dinwoody Glacier area.  Over two dozen miles from the trailhead and flanked by the largest glacier in the US Rockies, Gannett Peak features some of the most remote and technically demanding climbing of the continental US highpoints.  The demanding nature of this mountain, in addition to the technical and physical training needed for the climb, make Gannett Peak a worthy mountaineering objective on its own as well as an excellent training climb for bigger glaciated mountains.

What makes our guiding service unique is our educational focus that extends well beyond the summit.  Not only do we facilitate a safe and incredibly rewarding experience climbing Gannett Peak, our ultimate aim is to help you become a safer and more sustainable backcountry climber.  Our guides are talented, personable teachers who will help you develop new safety skills, useful snow, ice, and rock climbing techniques, as well as Leave No Trace best practices for backpacking, mountaineering, and alpine climbing.  For the most impactful educational experience, we highly recommend taking our Intro to Alpine Climbing Course to help you prepare for your Gannett Peak climb.
