The park is bisected by Bollinger Creek. To the west is Rocky Ridge, accessible from the parking lot via a paved road that brings hikers near the 2,024-foot summit. At the 1,760-foot elevation you can hike westward along a trail managed by the East Bay Municipal Utility District to the Valle Vista Staging Area on Canyon Road in Moraga, or south to the Chabot staging area in Castro Valley. A permit is required for hiking on EBMUD lands. Call 510-287-0459 for more information.
