Farallon Islands National Wildlife Refuge

The Farallon Islands, or Farallones, are a group of islands and sea stacks in the Gulf of the Farallones, off the coast of San Francisco, California, United States. The islands are also sometimes referred to by mariners as the Devil's Teeth Islands, in reference to the many treacherous underwater shoals in their vicinity. The islands lie 30 miles (48 km) outside the Golden Gate and 20 miles (32 km) south of Point Reyes, and are visible from the mainland on clear days. The islands are part of the City and County of San Francisco. The only inhabited portion of the islands is on Southeast Farallon Island (SEFI), where researchers from Point Blue Conservation Science and the U.S. Fish and Wildlife Service stay. The islands are closed to the public.

  • Acreage: geodesic area of the published polygon. The agency’s official acreage can differ where the boundary includes water, easements or inholdings.
