Access Issue: Trails are closed from sunset to 6:00 am. Details

Trails close at sunset. Give yourself enough time to be back at your vehicle (or campsite if you're staying at one) before dark, or the rangers will fine you.

Always visit the Castle Rock State Park website parks.ca.gov/?page_id=538 for fairly current official information.

Description

A collection of (primarily) rope climbing areas that are in the same general area and with a similar approach. Many of these areas are popular and can get crowed on the weekends despite being a little further out.

Includes California Ridge, Underworld, Chew Tooth, Platypus, Shady and the Gods.

Getting There

It takes about 15-30 mins to hike to these areas.

There is a brand new trail leading down to the Underworld, the Gods, Henry & Otis, Mud Wall and Mudlet. Please use the new path down instead of the old eroded trail.
