Monterey Bay Aquarium Added to CityPass
In April, the Monterey Bay Aquarium, in Monterey, Calif., became the newest addition to the San Francisco CityPass program. Travelers taking part in the program will now have the choice between visiting the Aquarium of the Bay at Pier 39 on San Francisco’s Embarcadero waterfront, and heading to the Monterey Bay Aquarium, located two hours by car south of San Francisco.
