What each one is.

Six Flags St Louis

A Hurricane Harbor water park is included with admission during summer.

Missouri school holidays, Fright Fest and Holiday in the Park events drive Six Flags St. Louis's peak crowds. Weekdays in May, September and October stay much calmer, with queue times on most rides dropping into single digits. Check live wait times for Boss and Mr. Freeze first thing on arrival, and use our crowd calendar to pick a quieter midweek date for marathon coaster sessions.
