You can spend your entire visit in the Embarcadero and not see it all. Get to know local marine life at Pier 39, home to both lounging sea lions and the Aquarium of the Bay. You can also catch a tour to Alcatraz Island here. A recent addition to the waterfront is the child-friendly Exploratorium at Pier 15, an interactive museum delving into science, art and human perception. Take a break for a bite to eat at the Ferry Building Marketplace, which hosts restaurants and vendors selling artisanal cheeses, wines, fresh produce, breads and seafood, before taking a ferry across the bay for a different view of the city.
