Access Issue: RAIN, WET ROCK CLOSURES; The sandstone around Castle Rock is fragile and is very easily damaged when it is wet. Details

WET ROCK: Holds rip off and climbs have been and will continue to be permanently damaged (like Donkey Dong and countless others) due to climbers not respecting this phenomenon. After a heavy storm the rock will remain wet, sometimes for several days. PLEASE DO NOT CLIMB AT CASTLE ROCK during or after rain.

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

This is re-re-discovered small bouldering area in Sanborn-Skyline park. It is definitely more secluded than Castle Rock/Indian Rock - you are likely to have whole area all to yourself.

Getting There

Going south from Hwy 35/9 intersection, pass Castle Rock parking lot and continue for two more miles. Turn left (east) onto parking lot labeled "Sunnyvale Mountain".

From parking lot hike north past fire road gate for 100 yards until first fork - keep left and keep walking until you see an obvious boulder (Tree-In-The-Wall) in about 100 yards.

Total approach time is around 5 minutes.
