This 373-acre island preserve in San Francisco Bay is a bird sanctuary to over 18 species of birds, has a colorful history, and provides wonderful views of the Bay Area from its 160′ rocky peak. You may only access Brooks Island as part of a scheduled East Bay Regional Park District naturalist tour. The Park District offers two kinds of naturalist-led kayak tours: “bring-your-own-boat” trips and outfitter-led trips.
