About Kings Island
About 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.
