Nike Missile Site


Thursday, May 18, 9:30 a.m.-3 p.m. 
Fees $70R / $81NR
Activity Level 2


During the tense years of the Cold War, 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 works in partnership with the Golden Gate National Recreation Area on the continuous take of restoration at site SF-88L, the only fully restored Nike Missile site in the country. This museum is an enduring reminder of the Cold War and their influence on today's society. Your knowledgeable volunteer guide will tell you about the history and the amazing buildings of the Nike Missile, how they arrived, assembled and stored. This tour will involve some light walking (no hills, some steps) to various outbuildings on the site. A boxed lunch will be provided to enjoy after the tour in the picnic areas at the site. Meet at the Hacienda de las Flores, 2100 Donald Drive., in Moraga.
