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

Climb the large chimney in the middle of the rock. Nudge, squirm, jam, and any other moves can and will be used to get you up this chimney. All the moves are rests, so running out of gas is not an issue.

Crux is getting through the bulge towards the top of the route.

There's also an interesting cave in the middle of the route that heads beck a ways into the rock.
