About each park

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.

Six Flags Discovery Kingdom

Six Flags Discovery Kingdom sits in Vallejo, California, on San Francisco Bay's northern edge. The park combines a theme park with a marine-animal section, running coasters like Medusa (the West Coast's first floorless), Kong (an inverted coaster), Superman: Ultimate Flight, Joker 4-D Free Fly Coaster, and the newer DC Stunt Coaster. Dolphin, sea lion and bird shows run throughout the day.

Bay Area weekend visits, California school holidays, and the Fright Fest event drive Discovery Kingdom's peak crowds. Weekdays in April, September and October are dramatically quieter, with queue times on most rides staying short. Check live wait times for Medusa and Superman on arrival, and use our crowd calendar to pick a midweek date for shorter waits. The bayside setting makes for pleasant walking even on quieter days.
