What can I see and do at Gannett Peak?

Climb It
Recommended for experienced climbers and mountaineers only. The most popular route is a multi-day backpacking route that begins at the Elkhart Park Trailhead (just a few miles from downtown Pinedale). At roughly 40 miles round-trip, the trail passes Island Lake and leads to Titcomb Basin, where most climbers set up their basecamp. To summit the peak, climbers will encounter a long day by climbing over Dinwoody Pass and following the Gooseneck Route to the top. Gannett Peak is best climbed in July and August. Climbers will need a variety of gear including ropes, ice axes, and crampons.

Camp in Titcomb Basin
If you aren't up for the climb, consider a multi-day backpacking trip to Titcomb Basin, in the heart of the Wind River Range. The Wind Rivers offer spectacular scenery that is utterly remote.
