04 · The parks

What each one is.

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.

The Wizarding World's Hogsmeade is the park's most iconic area.

Like its sister Studios park, Islands of Adventure stays busy year-round, with Hagrid's and VelociCoaster consistently posting the longest queues. Peak periods are US school holidays, Halloween Horror Nights and Christmas. Check live wait times immediately on arrival and head to Hagrid's first.
