Explore San Diego

San Diego is the second largest city in California and a great spot to hit the beach and catch some rays! With 68 miles of beaches, year-round mild temperatures, and plenty of sunshine, San Diego is a top destination for surfing, snorkeling, watersports, and more. From fresh and delicious Mexican food and beautiful weather to a rich cultural history, there’s no question that San Diego lives up to its nickname as America’s Finest City!

With downtown San Diego just a quick drive or bus ride along the bay from the airport, you can get off the plane and head right into the action! Kids and adults alike will love seeing pandas at the world-famous San Diego Zoo. History buffs shouldn’t miss touring the USS Midway Aircraft Carrier Museum, the Old Point Loma Lighthouse, and California’s first mission, Mission Basilica San Diego de Alcala, which now hosts a small museum. And no trip to San Diego is complete without a visit to Balboa Park, home to the botanical gardens, the Museum of Man, the Museum of Natural History, and the San Diego Museum of Art.

There are endless options when it comes to spending time outdoors, from beaches to boardwalks and hiking trails. Rollerblade or skateboard your way down Mission Beach Boardwalk, enjoy a swim at the laid-back Coronado Beach, hike through 1,750 acres of unspoiled land at Torrey Pines State Reserve, and enjoy the sunset at Sunset Cliffs Natural Park. End your day in true Southern California style with a Cali Baja burrito and a locally brewed IPA!
