Columbia College - Climbing

Review

Intro

The Columbia College boulders are sculpted marble limestone left after being mined out during the Gold Rush. The boulders are on the campus of the local community college, with most in a small nature preserve known as the Arboretum. Or, you can visit the nearby Columbia State Park for additional climbing.

What Makes It Great

The rock formations here are beautiful and unique, with a high concentration of high-quality difficult and moderate climbs. Watch for the poison oak that's everywhere -- even in spots that don't look covered in leaves. And be sensitive to campus security and state park staff. Columbia College boulders are divided into a number of areas. The most popular is the Arboretum. Tripple Cracks is a beautiful V7. There are good options for beginners to intermediates and strong climbers, with enough problems to spend the day.

Who is Going to Love It

The bouldering here is fun, though the weekday only access makes it more suitable for after-work problems or a quick workout.
