Bus in San Francisco

Muni operates bus, streetcar and cable-car lines. Buses and streetcars are interchangeably called Muni, but when streetcars run underground beneath Market St, they're called the Muni Metro. Some areas are better connected than others, but Muni spares you the costly hassle of driving and parking – and it's often faster than driving, especially along metro-streetcar lines J, K/T, L, M and N.
