Several ferry lines run out of San Francisco. Blue & Gold Fleet operates a number of lines, including service to Alcatraz ($11.50-$16), Angel Island ($13.50), Sausalito ($7.50 one-way), and Tiburon ($7.50 one-way). Tickets are sold at Pier 41 (next to Fisherman's Wharf), where the boats depart (there are also weekday commuter ferries to Tiburon from the Ferry Building). Golden Gate Ferry runs daily to and from Sausalito and Larkspur (each costs $6.45 one-way), leaving from Pier 1, behind the San Francisco Ferry Building at the foot of Market Street on the Embarcadero. The Alameda/Oakland Ferry operates daily between Alameda's Main Street Ferry Building, Oakland's Jack London Square, and San Francisco's Pier 41 and the Ferry Building ($5.50 one-way); some ferries go only to Pier 41 or the Ferry Building, so ask when you board.
