Old Town Trolley
You can buy a day or two-day pass on San Diego’s green and orange Old Town Trolleys, hopping on and off to explore points of interest all along its lines, such as the Midway Aircraft Carrier Museum, Gaslamp Quarter, or even take it all the way to Coronado Island. Special tours include a La Jolla and San Diego
Beaches Tour and “SEAL” (Sea and Land) tour, which travels via amphibious buses. Cruise passengers can purchase a two-hour tour with hop on and off privileges at 10 different stops right from the cruise ship terminal ticket booth.
