We’ll begin our day at Fort Baker on a self-guided tour. Bring your own picnic lunch and after the walk, you’ll have time to eat before traveling to the Nike Missile Site. The Nike Missile Site is a Cold War museum on the Marin Headlands. During the tense years of the Cold War from 1953 to 1979, the United States Army built and operated close to 300 Nike missile sites in the United States. These sites were designed as the last line of defense against Soviet bombers. Today, a dedicated group of volunteers work in partnership with the Golden Gate National Recreation Area on the continuous task of restoration at site SF-88L, the only fully restored Nike missile site in the country.
