Climbing

The Teton Range has some of the nation's most diverse mountaineering. Excellent rock, snow, and ice routes abound. Unless you're already a pro, it's recommended that you take a course from one of the park's concessionaire climbing schools before tackling the tough terrain. Practice your moves at Teton Boulder Park, a free outdoor artificial climbing wall in Phil Baux Park at the base of Snow King Mountain.
