BART also connects to Oakland and the East Bay from San Francisco via a tunnel running under San Francisco Bay. Passes are required for the use of BART trains, and can be conveniently purchased from machines at any BART station. MUNI and BART are separate systems. Passes are not interchangeable between the two, even though they do have some common underground stations. The few existing lines do serve a genuine public transportation service and deservedly have been designated a historic public landmark.
Cable cars have a unique fare structure and rules.
Please link to Cable Cars for the most current information. The South of Market district has more liberal parking than The Castro, but is still very limited. Most metered parking in The City is free on Sunday, but not all . Do not attempt to park anywhere where parking signs or curb markings prohibit. Violators will be towed.
