Situated on a 130-acre salt marsh, this former military airfield is now part of the Golden Gate National Recreation Area. The waterfront extends from the marina to the base of the Golden Gate Bridge, drawing runners, dog walkers, and bikers. The park also includes a sand beach, picnic tables, and panoramic views of Alcatraz and the bridge. The visitors’ center showcases local sea life, while the Crissy Field Center features exhibitions and programs that teach children about urban environmental issues. The Warming Hut, housed in an old army shed, is a great place to grab coffee and a snack.
