Snow usually melts from valley trails, approximately 6,700 feet by mid-June but remains in parts of the high country through much of the summer. Safe travel over Paintbrush, Static Peak and Moose Basin Divides and Hurricane, Mt. Meek and Fox Creek Passes requires an ice axe and knowledge of its use as late as August. Snow conditions vary from year to year. If you are planning to cross any divides before mid to late July, and do not have the skills for safe use of an ice axe on steep snowfields, consider an alternate route. Not crossing these divides essentially takes out the possibility of a loop trip or a Teton Crest Trail trip. However, there are still opportunities for a rewarding “in and out” trip utilizing any of the major canyons.
Permits are not required for mountaineering, but climbers on overnight trips must have a backcountry permit to camp or bivouac. Weather changes rapidly between extremes, impacting climbing trips to the Teton Range. It’s important to check current local weather and mountain conditions prior to your visit.

All backcountry users are required to carry Interagency Grizzly Bear Committee approved bear canisters. Canisters can be checked out at all permit issuing stations free of charge with a backcountry permit.

Permits for these sites can be obtained on a first-come, first-served basis at Moose or Colter Bay permit offices in Grand Teton National Park, although the Colter Bay office is the closest to the campsites.
