My job took me to the waterfront area of the city, specifically around the tourist attraction of Pier 39. On the northeast part of where the city meets the bay, the pier is a collection of shops and restaurants with entertainment venues including an aquarium. From the back of the pier, there are great view of the bay, Alcatraz, Angel Island and both bridges that span the bay.
Also, from here you can board ferry boats to Alcatraz, Angel Island, or Tibouron(sp?). Ferry tours of the bay launch from here as well. Off to the west, Fisherman's Wharf is an adjacent tourist spot.
