The only restored Nike missile site in the country - SF-88

This was an amazing tour into the history of the Cold War period in time. I got a full tour of the extremely high-security facility. In its time you would be shot coming in this place if you were not authorized. I highly recommend coming here for a tour if you're in the Bay Area.

From their site:

The Cold War was a tense time between the United States and the Soviet Union, two superpowers vying for global influence. To defend against potential Soviet attacks, the US Army built close to 300 Nike missile launch batteries between 1953 and 1979. The Nike missiles were intended to be a last desperate act of defense against H-Bomb carrying Soviet bombers that had eluded interceptor jet aircraft.

Missiles at the Nike sites also could have carried nuclear payloads that would have detonated off the coast of the California communities that housed them. SF-88 in the Marin Headlands was one such site. Today, GGNRA preserves the site as it was during operations to remind visitors of the physical effects of the Cold War on the American landscape.

Currently, SF-88 is open Saturdays, 12:30 p.m. to 3:30 p.m. On the first Saturday of each month, there is an open house with volunteers and Nike veterans interpreting the history of the base. Open days are extended during the summer. To confirm hours or if you have any questions, please contact 415-331-1540.
