Access Issue: Falcon Nesting Closure at Castle Rock Details

Description

This mixed area sits inside of Mt. Diablo State Park southeast of Walnut Creek, and northeast of Danville. Offering a mixed bag of climbing: trad, top rope, and sport routes are all found here. Additionally, there is some bouldering, but not at the major established climbing areas.

Access to the park will cost you up to $7 per car, so heads up. You can check the park website directly for current prices and information.

Most of the climbing is on sandstone, which makes the sport bolts sketchy, and some of the trad routes absolutely terrifying. It also makes for some fun smearing and edging moves everywhere.

Almost all areas have a simple way to set up a toprope, though you should bring really, really long slings (20' +) for many of the anchors.

Getting There

Boy Scout Rocks: From the 680 just north of Danville, take exit 40 for El Cerro Blvd and follow that east for about 1 mile. Continue on Diablo Road. After about 2 miles, turn left at Mount Diablo Scenic Blvd, which becomes South Gate Road. Boy Scout Rocks will be on the right. Boy Scout Rocks Map

Pine Canyon: From Walnut Creek, take the Ygnacio Valley Road exit and drive east for about 4 miles. Turn right at Oak Grove Road and continue on Castle Rock Road to its end. Pine Canyon Map

State park entrance fees have increased to $10. Bring your loot people! May 13, 2010
There is soo much potential here if you don't mind finding the good rock among the bad. It's like the ugly cousin of red rocks. If this place gets more developed it will need a guidebook of its own. A fun adventure!

Park now costs $10 per car or $9 for seniors so bring your grandma! Oct 4, 2012
Please do not climb in this area if it has rained in the past 3 days. Not only does it damage the rock but it's very dangerous as the sandstone crumbles easily when wet. I thought most people knew this, but I saw several people climbing today even though it had rained heavily the night before. Nov 28, 2016
