Petit Grepon: The South Face

Petit Grepon Alpine Rock Course

This 2 day Petit Grepon course focuses on preparing to and climbing a multi pitch alpine route in Rocky Mountain National Park. By the end, students will have experienced an alpine rock route in RMNP. This course covers the logistics required to climb a multi pitch rock route with a planned bivy the night before the climb. A bivy permit, light weight camp set ups, and food planning will all be a part of this experience.

The Petit Grepon, Glacier Gorge, Rocky Mountain National Park

This course will include multi pitch climbing preparation, good communication, and improve technical climbing skills. This course is also designed to give the intermediate climber the experience of climbing alpine rock route in RMNP and build efficiency. The South Face III 5.8 on Petit Grepon is a popular objective for this course.  We recommend taking the Rock Climbing Development Series Level 1 Course or have similar experience before taking this course.
