What each one is.

Kings Island

Kings Island is a huge theme park in Mason, Ohio, just north of Cincinnati. It's one of the Cedar Fair (now Six Flags) parks and runs a strong coaster line-up: The Beast (the world's longest wooden coaster, opened 1979), Diamondback, Mystic Timbers, Orion (a giga coaster), Banshee (the world's longest inverted coaster), and Racer. A full water park operates on the same site during summer.

The Ohio summer school break and Halloween Haunt event drive Kings Island's busiest periods, with weekend queue times on Orion and The Beast often exceeding 90 minutes. Weekdays in May, September and October are dramatically quieter. Check live wait times on arrival, and use our crowd calendar to pick a midweek visit if you want to ride everything in a day.

The coaster line-up includes Mr. Freeze: Reverse Blast, Boss (a large wooden coaster), Superman: Tower of Power drop tower, American Thunder wooden coaster, and Batman: The Ride. 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.
