Over the last 160 years, industrial and recreational uses changed the environment of San Francisco`s northern waterfront. Stroll with a Park Ranger to discover the history of this vibrant area on a walking tour through the Aquatic Park Historic Landmark District, the Cannery, Hyde Street Pier, and Fish Alley at Fisherman`s Wharf. The tour is one hour and covers approximately one mile, with some gently sloping and uneven terrain. Dress in layers, wear sunscreen, and good walking shoes.
