About Red Rock Island
Red Rock Island is an uninhabited, 5. 8-acre island in the San Francisco Bay located just south of the Richmond–San Rafael Bridge. The property is the only privately owned island in San Francisco Bay. The boundaries of three counties – San Francisco, Marin and Contra Costa – converge on this high rock.
