    The San Bernard Oak is accessible from County Highway 306 via an unpaved driveway and a 0.6-mile hiking trail.   Parking is available at the north end of the driveway.  

    The hiking trail is relatively level, with several stretches of boardwalk over seasonal wetlands.   Hikers may observe a rich diversity of plants and birds, and evidence of many mammals.
