    The island is not accessible to wheelchair users at this time. 


    The environmentally sensitive island is a marvelous bird sanctuary. Over 18 species of birds nest there, including Caspian Terns, Black-crowned Night Herons, gulls, and ducks. The island also supports an unusual variety of plant communities, including native Coastal Grassland that persists in a relatively undisturbed state. There is also a salt marsh and many acres of Northern Coastal Scrub. In spring, the wildflowers put on a colorful show.

Both trips include a Naturalist guided two-mile hike around the island, which is normally closed to visitors.

    The island's original inhabitants were Ohlone Indians who lived there for thousands of years. Later, in the early 19th century, it became part of Rancho San Pablo. With the advent of European settlers, the island was used for sheep and cattle grazing, oyster-raising, and extensive quarrying. Over the years, Brooks Island has had many owners and has been known by a variety of names, including Isla de Carmen, Rocky Island, Bird Island, and Sheep Island. The East Bay Regional Park District acquired the island in 1968.
