By Public Transport
San Francisco is one of the few American cities with a good public transportation network and a third of its citizens use it.
The combined light rail/subway system known as Muni Metro is complimented by a good network of no-emission buses, as well as the iconic cable car system and a historic streetcar line (the F).
In addition the commuter rail network BART (Bay Area Rapid Transit) links the city to the East Bay cities of Oakland and Berkeley and beyond, and to San Francisco International Airport (SFO) to the south of the city.
There is also the Caltrain runs from San Francisco along the Peninsula down to San Jose (Silicon Valley).
Long-range bus services and regional buses to destinations including Sonoma, Napa and Marin have terminals in San Francisco.
A small fleet of commuter and tourist ferries operate across the Bay from the Ferry Building and Pier 39 to Marin County.
Traffic generally flows well through the city, although parking is at a premium. You'd not need a car to explore this city, but many will prefer to hire one for exploring the extremely scenic hinterland. See our car rental recommendations. Interstate 80 goes to the East Bay, Interstate 280 runs south to San Jose, US 101 goes to Silicon Valley.
Cycling is a popular pastime in the Bay Area (mountain biking was invented in Marin), and the city caters to cyclists.
