Explore San Diego
Pack your swimsuit and get ready to catch some rays in America’s Finest City! San Diego has over 68 miles of beaches, making it a favorite destination for surfers, families, and watersport enthusiasts alike. Choose from spots like La Jolla Shores, a popular beach for kayaking, snorkeling, and scuba diving; laid-back Coronado Beach; and the classic Southern Californian Mission Beach Boardwalk. San Diego’s outdoor activities go beyond the beach, with hiking trails through the salt marshes and waterfowl refuges of Torrey Pines State Reserve and sunset views from the coastal bluffs of Sunset Cliffs Natural Park.
It’s a quick drive, bus ride, or even bike trip from the airport to downtown San Diego, so you can head straight into the action after landing! Stroll through the historic Gaslamp Quarter and explore the many shops, restaurants, and galleries this district of restored Victorian buildings has to offer. Not far from downtown is the city’s renowned Balboa Park. This Spanish-style park was built for the Panama California Exhibition of 1915-1916, and many of the original buildings still stand. Today, the park is home to botanical gardens, the Museum of Man, the Museum of Natural History, the San Diego Museum of Art, and the San Diego Zoo.
