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 Upper Tier: A tall piece of sandstone about 90 feet tall 100 feet across. There are a handful of top-ropes, a weird crack, and an excellent mixed trad/sport line (The Route Formerly Known as Face (.10+)).

To reach the top of the Upper Tier from below, trek up the third class gully on the (climber's) left side of the rock. The obvious crack in the middle of the rock is known as Chouinard's Crack (5.9) and serves as an easy reference.

Do not climb for three days after a rain storm! The sandstone is fragile and needs time to dry out, otherwise it will break and scar.
