You may only access Brooks Island as part of a scheduled East Bay Regional Park District naturalist tour. Please call the Reservations Department at (888) 327-2757, option 2 or visit EBParks.org/Register for the current schedule of trips.
Brooks Island Regional Preserve includes both the 75-acre (30 ha) of Brooks Island above the low-tide line and 300 acres (120 ha) of the surrounding bay. The only public access to the island now is via an East Bay Regional Park District naturalist tour.
Brooks Island is a mostly flat strip of land extending from a round hill, named Jefferds Hill, which peaks at 160 ft (49 m) in San Francisco Bay, located just south of the Richmond Inner Harbor in Richmond.
Originally named as Isla de Cármen by a Spanish explorer, the island was named Brooks Island on California maps in 1853. The eponymous Brooks has never been identified. It has also been called Sheep Island and Rocky Island at various times. The island was bought by the regional parks district in 1968, and was opened to the public in 1988. Access is now available through ranger-led guided tours. - https://en.wikipedia.org/wiki/Brooks_Island_Regional_Preserve
