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.

Historically, Castle Rock has specialized in planning picnic activities for large groups of 300 or more, but in 2007 the East Bay Regional Park District started to renovate the park for both drop-in and reservable picnic use. There may also be a catering service available. You can make reservations by calling 888-327-2757, press choice 2. Remember that from the front gate there is no shuttle service to the park. Bring your heavy or bulky items with a wagon. The trip to the pool area from the front gate is a one-quarter mile, a six-minute walk on average. The drive to the pool area from the Orchard Staging Area is half a 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.
