San Francisco Subway

The subway system in San Francisco is convenient and easy to use, although it is not as interesting for tourists as the cable cars and streetcars. It is particularly useful to get to and from the airport.

The subway system is operated by two different companies: MUNI and BART. The two companies share four stations in the city center: Civic Center, Powell, Montgomery, and Embarcadero.

In order to switch between the two networks, it's necessary to buy a ticket for each one.


BART (Bay Area Rapid Transport) is similar to a short-distance train system, and the BART lines link San Francisco to other cities and further away places. The network is used by over 400,000 people per day.

While BART travels to the areas further from the city, the MUNI Metro (Municipal Transport Agency) tours the heart of the city. We can describe it as a kind of light rail link, with underground as well as above-ground stations.


BART has 5 lines:

  • Yellow: Pittsburg/Bay Point - San Francisco Airport
  • Red: Richmond – Daly City/Millbrae.
  • Green: Fremont – Daly City.
  • Orange: Richmond – Fremont.
  • Blue: Dublin/Pleasanton – Daly City/Millbrae.


The BART fares vary depending on the distance traveled. Journeys can cost between US$ 2.50 and US$ 12.90

To calculate the fare, you just need to look at the map which shows the different BART lines and stations. There you can see how much a journey between two particular stations costs.

Times and Frequency

During the week, the train runs from 4 am until midnight. On Saturdays, it starts running at 6 am and on Sundays at 8 am. Outside of these times, there are night buses that cover the same routes.

The trains run every 15 minutes, or up to every 20 minutes at quieter times.


While BART reaches places further away, the MUNI Metro, run by the San Francisco Municipal Transportation Agency goes around the city center. It's basically a light railway system with both underground and overground stations.


The MUNI network has 6 regular lines and one special line (S) which operates during rush hour. Although a number of lines have the same start and finish point, they all travel along different routes:

If you're going to stay in the city for a few days, it's worth having a look at the Muni Passport or the CityPASS.

Times and Frequency

The Muni metro trains run every 7-10 minutes and, approximately and depending on the station, run between 5 am and 1 am. Outside of these times, there are night buses that travel along the L and N routes.
