About The Park

Within Diablo Foothills Regional Park is the Castle Rock Recreation Area which is located in a scenic canyon along Pine Creek. The area is dominated by oak woodlands and prominent sandstone formations.

Castle Rock has historically specialized in preparing picnic events for large groups of 300 or more people, but in 2007 the East Bay Regional Park District began renovating the park for drop-in as well as reservable picnic use. Catering service may also be available. Reservations may be made by calling 888-327-2757, press option 2. Note that there is no shuttle service into the park from the front gate. Bring a wagon to transport your heavy or bulky items. The distance from the front gate to the pool area is one-quarter mile, an average six-minute walk. The distance from the Orchard Staging Area to the pool area is one-half mile.

Diablo Foothills Regional Park, and Castle Rock Park are bordered by Mt. Diablo State Park and Walnut Creek Open Space, providing access to more than 18,000 acres of public lands.
