Within the compact city centre, walking is a pleasurable way to get around, but there's a solid transport network backing you up when perambulation seems too pedestrian. San Francisco's principal public transport system is Muni (San Francisco Municipal Railway), which operates nearly 100 bus lines (many of them electric trolley buses), streetcars and the famous cable cars. The Bay Area Rapid Transit (BART) system is a convenient, economical subway system linking SFO airport, the Mission District, downtown San Francisco and the East Bay. Ferries are a scenic way to get around.
Ferries are back in business, plying the waters from Fisherman's Wharf (Pier 39 and Pier 41), and the Embarcadero Ferry Building to Alameda, Oakland, Sausalito, Larkspur, Tiburon and the bay islands.
Where else can you travel in a tourist attraction from one tourist highlight to another? As well as getting you around town on its streetcar and bus routes, Muni offers a ride in one of San Francisco's famously rickety, old-fashioned, open-air cable cars. Two cable-car lines leave from Powell and Market Sts, and one leaves from California and Markets Sts.
