Six Flags Discovery Kingdom vs Worlds Of Fun

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.

Worlds of Fun is a theme park in Kansas City, Missouri, opened in 1973 and now run under the Six Flags banner. The park covers 235 acres with themed areas based on continents and a varied coaster line-up: Mamba (a 205-foot Morgan hyper coaster), Prowler (a GCI wooden coaster), Patriot (an inverted coaster), and Timber Wolf. An Oceans of Fun water park operates on the same site in summer.

Kansas City school holidays and the Halloween Haunt drive Worlds of Fun's peak crowds, particularly weekend days in July, August and October. Weekdays in May, September and early October are much quieter. Check live queue times for Mamba and Prowler before committing, and use our crowd calendar to pick a lower-crowd midweek date for shorter waits.
