On clear San Francisco days, the view doesn't get much better than the one from Crissy Field. In addition to setting their sights on the Golden Gate Bridge or Alcatraz Island, visitors can relax on the beach or have a snack in the picnic area. Adventure-seekers also enjoy this former military airfield for windsurfing offshore.
