SeaWorld has been a longtime favorite in San Diego since 1973. The marine theme park brings dolphins, orcas, sea lions, penguins, sharks and other sea creatures together in a variety of attractions, shows and exhibits, including indoor and outdoor aquariums. A visit allows guests of all ages to learn in a fun, engaging environment. SeaWorld also has thrill rides like the Mantis and Electric Eel roller coasters. Round out a day in the park with shopping and dining excursions while making the most of your time in the gorgeous California sunshine.
