Access Issue: Falcon Nesting Closure at Castle Rock Details

Castle Rock in Pine Canyon and the Wanna Get Away areas are closed for peregrine falcon nesting season, from February 1 through July 31st every year. All other Mount Diablo area crags are open to climbing. The news release is linked here parks.ca.gov/NewsRelease/493.

Description

The biggest rock at the bottom of the canyon. This rock has high foot traffic from both day hikers and stoners alike so don't leave stuff laying around on top.
