The Farallon Islands, part of the US National Wildlife Refuge system, are comprised of 4 groups of small, rugged islands located approximately 30 miles off the coast of the State of California.
They consist of Southeast Farallon, North Farallon, Middle Farallon, Noonday Rock, and South Farallon. They are, with the exception of Southeast Farallon, part of the Farallon Wilderness Area. They are also designated as a State Ecological Reserve and Golden Gate Biosphere Reserve.
Southeast Farallon is the only island with structures. These are leftover from an earlier time and are used for residential purposes by scientific and maintenance people when working on the island.
These islands have been said to be the location of the largest colony of nesting seabirds south of Alaska with approximately ¼ of the California breeding population taking place here.
As well, they also have the largest Western Gull colony in the world and support half the world's population of the Ashy Storm Petrel. Other seabird species nesting here can include the Leach's Storm Petrel, Fork-tailed Storm Petrel, Double-crested Cormorant, Brandt's Cormorant, Pelagic Cormorant, Black Oystercatcher, Common Murre, Pigeon Guillemot, Cassin's Auklet, Rhinoceros Auklet, and Tufted Puffin.

History and Use
Areas of Interest
Access and Facilities
Access onto the islands, by the general public, is not allowed. This stance is due to various reasons that can include protection of the wildlife and birds, lack of docking facilities on most of the islands, and lack of facilities for visitors.
Access is restricted, by and large, to scientific efforts and maintenance needs. However, interested parties can apply to volunteer their time to assist in certain maintenance type jobs.
Marine access to the waters around the islands is possible, but is restricted and controlled.
Since these islands are off the California coast, west of San Francisco, the closest commercial airport supporting scheduled air service will be San Francisco International Airport (SFO).
Consult a trusted travel professional for specific, up-to-date information.
