Welcome to Pigeon Point Light Station!

Perched on a cliff on the central California coast, 50 miles south of San Francisco, the 115-foot Pigeon Point Lighthouse, one of the tallest lighthouses in America, has been guiding mariners since 1872. Its five-wick lard oil lamp, and first-order Fresnel lens, comprised of 1,008 prisms, was first lit at sunset, November 15, 1872. The lens stands 16 feet tall, 6 feet in diameter, and weighs 8,000 pounds. It sits in a lantern room that had been constructed at the Lighthouse Service's general depot in New York before being shipped around the Horn. Although the original Fresnel lens is no longer in use, the lighthouse is still an active U.S. Coast Guard aid to navigation using a 24 inch Aero Beacon.

The Pigeon Point Hostel
The Pigeon Point Lighthouse hostel is operated by the Golden Gate Council of Hostelling International, a nonprofit membership organization, with cooperation from the California Department of Parks and Recreation and the United States Coast Guard.

In 1960 the US Coast Guard built four, three-bedroom houses next to the lighthouse. Today, through the efforts of Hostelling International, these structures offer overnight lodging for up to 50 hostellers of all ages. Each house has three male or female bunkrooms; separate bunkrooms may be reserved for families and couples. Guests share bathrooms with hot showers, fully-equipped kitchens and living rooms. Meeting space is available. An outdoor hot tub may be rented in the evening. 

Tried for nearly 30 inutes to find this one and nothing to be found. Checked the pics and this cache is definately a no go.
