City: Walnut Creek Park: Castle Rock Regional Recreation Area
The first of three increasingly difficult hikes culminating in a hike to Mt. Diablo Summit. A 9.5-mile out-and-back hike from Castle Rock Park to BBQ Terrace with about a 1600-foot elevation gain. And a possibility of increasing the distance and elevation gain by returning via Wall Point instead of straight back. Route is Stage and BBQ Terrace Roads. A short rest/snack stop at BBQ Terrace before the return. Water and restrooms at Castle Rock Park and BBQ Terrace. No dogs are allowed in Mt. Diablo State Park. Meet at the restrooms about ¼ mile in from the trailhead. Trailhead address is 1700 Castle Rock Road, Walnut Creek. Please arrive at least 15 minutes early in case you have to park in the Orchard area and walk ¼ mile to the trailhead.Contact: Howard
