Explore San Diego.

Layer on the sunscreen and get ready to catch some rays in sunny San Diego! The destination nicknamed America’s Finest City has over 68 miles of beaches, making it a favorite spot for surfers, families, and watersport enthusiasts alike. Choose from beachy spots including La Jolla Shores—popular for kayaking, snorkeling, and scuba diving—classic Mission Beach Boardwalk, and laid-back Coronado Beach. Tired of the beach but still want to enjoy the weather? Partake in other outdoor activities such as hiking through the salt marshes and waterfowl refuges of Torrey Pines State Reserve and whale watching at Sunset Cliffs Natural Park.

San Diego, the oldest city in California, has a rich cultural history and many notable landmarks. Take a tour of the USS Midway Aircraft Carrier Museum—one of the United States military's largest ships—or visit the museum at California’s first mission, Mission Basilica San Diego de Alcala. Wander through the shops and galleries in the historic Gaslamp Quarter and admire the restored late-19th- and early 20th-century Victorian buildings.

Downtown San Diego is just minutes from the airport, so your vacation can get started right away! Kids and adults alike will love a visit to the world-famous San Diego Zoo. And no trip to San Diego is complete without visiting Balboa Park, home to the botanical gardens, the Museum of Man, the Museum of Natural History, and the San Diego Museum of Art.
