A coastal city in the far south-west of California, on the Pacific Ocean just north of the border with Mexico.
San Diego occupies a large natural harbour on the southern California coast and has a long association with the US Navy. Its mild, dry climate supports outdoor life year-round. Common stops include Balboa Park and its zoo, the Gaslamp Quarter downtown, the USS Midway Museum, and the coastal districts of La Jolla and Mission Beach.
