Pier 39 is the ultimate tourist attraction. The pier has two levels filled with both cheap and expensive restaurants, including Bubba Gump's, Pier Market and Boudin Sourdough Bakery. There are several kid friendly attractions such as a double-decker carousel and an aquarium. I love all the unique stores on Pier 39, my favorites being the Sock Shop, Le Beastro, Making History and We Be Knives. Pier 39 has a lot of great photo ops, especially at the end of the pier where you can view the Golden Gate Bridge, Alcatraz, and the famous seals! Parking is expensive and hard to find if the lot is full and on the weekends it gets very crowded on the pier. However I highly recommend Pier 39 for visitors or people who haven't been before as they have something for everyone, especially kids and pet owners!
