Castle Rock Recreation Area
About The Park
Adjacent to Diablo Foothills is Castle Rock Recreation Area 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 beginning in 2008.
Besides Diablo Foothills, Castle Rock Park is bordered by Mt. Diablo State Park and Walnut Creek Open Space, providing access to more than 18,000 acres of public lands. Back to top
Park Activities
Castle Rock offers seven reservable picnic sites, volleyball courts, softball fields and a swimming pool. Other picnic sites are available on a first-come, first-serve basis.
Swimming
The pool complex features a 30 feet by 70 feet swimming pool and deck areas. In addition, the complex is fully accessible to individuals with disabilities, including the bathhouse and an accessible lift into the pool. (Beach access fee to enter swim area.) Swimming is allowed only when lifeguards are on duty. For current hours of operation and lifeguard service schedule, visit the Swim Facilities page. Back to top
