Explore San Diego

Layer on your sunscreen and get ready to soak up some rays on over 68 miles of beaches! Multifaceted San Diego is a favorite destination for surfers and culture-lovers alike, offering its visitors beaches, scenic hiking trails, numerous museums, great food, and more.

With miles of Pacific coastline, San Diego is a prime beach destination. Rollerblade or skateboard down Mission Beach Boardwalk and stop at seaside Belmont Park for a ride on the Giant Dipper Roller Coaster. Play a few rounds of beach volleyball on the courts at Moonlight Beach, snorkel and scuba dive at La Jolla Shores, or relax in the sun at laid-back Coronado Beach. If nature walks are more your speed, watch for whales on the coastal bluffs at Sunset Cliffs Natural Park, explore over 1,750 acres of land including salt marshes and waterfowl refuges at Torrey Pines State Reserve, or enjoy a walk or bike ride through Balboa Park.

San Diego is California’s oldest city, and is full of historic monuments and cultural destinations. In Balboa Park alone, visitors have their pick of the San Diego Zoo, the San Diego Museum of Art, the Japanese Friendship Garden, the San Diego Automotive Museum, and the Museum of Man, just to name a few options. Take a trolley tour of downtown San Diego, gallery-hop your way through the historic Gaslamp District, or enjoy a concert at the San Diego Symphony. Don’t forget to sample some of the local California-Baja fare and try burritos, tacos, and more made with fresh local produce and Mexican-inspired flavors. And when it’s time to say goodbye, the airport is just a short car, bus, or bike trip from downtown!
