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.
Annual Closure Notice
The annual closure area for pilgrim falcons protection is in place from 1 February to 31 July. It encompasses the whole area of rock formation east of the Stage Road. All the trails that lead to this area are unofficial trails and are not on the map of the park. Watch for signs indicating closed areas. All officially named trails are accessible and not impacted by this protected area throughout the park.
Basketball courts, pits for horseshoes, a volleyball court, softball field, and picnic sites are now open to the everyday public. There are four sites with a capacity of 100 and 3 that can be reserved with a capacity of 50 and can only be reserved by calling the 888 number. On a first-come, first-serve basis, other picnic sites are open.
The swimming pool complex has a 70-foot swimming pool and deck areas of 30 feet. The building is also fully accessible to disabled people, including the bathhouse and an accessible lift into the pool. (Swimming pool access fee.)
