Public Transportation (Trolley & Buses)
Public transportation in San Diego is operated by the San Diego Metropolitan Transit System. The San Diego Trolley (light rail) connects key areas like Downtown, Old Town, Mission Valley, and the border. Buses provide extensive coverage across the city and reach places not served by the trolley. The system is affordable, and contactless payments or PRONTO cards make travel easy. It’s one of the best ways to get around central San Diego.
