San Vicente Mountain Park, located 2.7 miles west of the 405 freeway on an unpaved section of Mulholland Drive, has awesome 360-degree views and access to extensive hiking, mountain biking, and equestrian trails. The 10.2-acre park has public picnic areas, bathrooms, and is a gateway to Westridge Canyonback Park and the 20,000-acre “Big Wild” wilderness area. A short walk along a wide dirt road leads visitors to this historic site, which once housed a Nike-Ajax missile radar station during the Cold War (1956–1968). The original radar tower now provides panoramic views of the Santa Monica Mountains, Encino Reservoir, San Fernando Valley, and Los Angeles Basin, making it one of the best spots in the region to watch a sunset.
