Rock Climbing at Yosemite National Park

Yosemite Rock Climbing

Rock Climbing
The Yosemite Mountaineering School and Guide Service has been rock climbing in Yosemite since 1969. Our guides can take you where you want to go. As the only guide service permitted to operate in Yosemite National Park, we know Yosemite better than anyone and love sharing our knowledge and skills with you.

Many of our Yosemite climbing guides are AMGA certified and have decades of climbing experience in the park. All of our guides also hold Wilderness First Responder or Wilderness EMT certifications.

View the YMS activity deposit and cancellation policy.

In addition to rock climbing, the Mountaineering School provides group hikes, custom day hikes, and overnight backpacking trips. During the winter we move up to the Cross Country Ski Center at Badger Pass, where we offer cross country ski lessons, rentals, and overnight trips to our beautiful Glacier Point Ski Hut.
