With its bustling Gaslamp Quarter downtown and hip Little Italy restaurants, all in close range of the famous San Diego Zoo and the 17 museums of Balboa Park, there’s a lot to keep visitors busy in this city. And that’s even before you factor in San Diego’s waterfront, its majestic Star of India—the oldest operable tall-masted ship in the world—and its many fabulous beaches. Take a whale watching tour or explore its vast naval fleets from a harbor tour; visit the historical center of Old Town; take a tour of San Diego’s missions; and head to the stunning cliffs and tide pools of Cabrillo National Monument where the first European set foot in California in 1542.
