Both maritime and military mix with Mother Nature in this unique coastal city. For a taste of the life of good old sea salts, drop by the Maritime Museum and go onboard a centuries-old sailing vessel. The USS Midway Museum, meanwhile, pays tribute to a WWII-era aircraft carrier. When you get tired of all things naval, head over to Mission Beach and La Jolla to soak up some sun. You also shouldn't miss Balboa Park, a large green area adorned with museums and theaters.
