It is located in Eureka, Missouri, which is a suburb of St. Louis, Missouri.

It is the only one of the original three Six Flags parks to be both owned and operated by Six Flags. (The other two, Six Flags Over Texas and Six Flags Over Georgia, are owned by limited partnerships and operated by Six Flags.) The park was conceived by Six Flags founder Angus G. Wynne in the 1960s, although unlike the previous two Six Flags parks, it was designed by the Six Flags company itself rather than architect Randall Duell, who was preoccupied with designing AstroWorld at the time. Its layout consists of six themed areas, each of which contain numerous attractions, dining locations and live entertainment. Since its original opening in 1971, the park has undergone many changes, most notably of which are the replacement or renaming of all six of the park's original areas in the 1990s, as well as the addition of two new ones.
