Crissy Field

Transformed in 2001 from a defunct army airstrip to an ecologically rich recreation area, this 4.3-mile ocean-front promenade offers spectacular views of the Golden Gate Bridge and Alcatraz. Walk or ride the groomed trail (several nearby outfitters offer bike rentals, including Sports Basement) ending at Fort Point, built as a defensive structure during the Civil War. On foggy days, make a pit stop at the Warming Hut for warm beverages, organic soups and sandwiches and one of the best selections of unique San Francisco souvenirs around. If you’re eager for more activities along the route, check out the House of Air trampoline, Planet Granite climbing gym or La Petite Baleen swim school on the northwest side of the trail.
