About Seaworld San Diego
About Seaworld San Diego
SeaWorld San Diego sits on the shore of Mission Bay in San Diego, California. It's the original SeaWorld park, opened in 1964, and blends marine-animal exhibits with modern coasters: Emperor (a floorless dive coaster), Electric Eel (a triple-launch coaster), Manta (a launched family coaster), and the newer Arctic Rescue straddle coaster.
Southern California weather keeps SeaWorld San Diego open year-round, with peak crowds during US school holidays, Halloween Spooktacular and Christmas. Weekdays in January, September and October are dramatically calmer. Check live queue times for Emperor and Electric Eel on arrival, and use our crowd calendar to pick a midweek day for shorter waits. The park pairs well with a full-day visit to nearby San Diego attractions.
