Petit Grepon

South Face One of the top 25 routes in this collection!

Beta Images Slide Show

A superb route on an amazing feature. Fun, moderate, well-protected climbing on excellent rock with exciting exposure will take you to a summit where you'll never get the entire climbing party for a photo. If you don't like this one, consider taking up another sport. Be sure you contact the Rocky Mtn. Park backcountry office if you're planning to camp below the Petit Grepon - you must have a permit, can't use a tent, and there are other restrictions you need to know about (also see the references).
