Pier 39 is a shopping center and popular tourist attraction built on a pier in San Francisco, California. At Pier 39, there are shops, restaurants, a video arcade, street performances, the Aquarium of the Bay, virtual 3D rides, and views of California sea lions hauled out on docks on Pier 39's marina. A two-story carousel is one of the pier's more dominant features, although it is not directly visible from the street and sits towards the end of the pier. The family-oriented entertainment and presence of marine mammals make this a popular tourist location for families with kids.
