What each one is.

Kennywood

Kennywood is a historic traditional amusement park in West Mifflin, Pennsylvania, just outside Pittsburgh. It has been running since 1898 and is a US National Historic Landmark - home to three classic wooden coasters (Thunderbolt, Jack Rabbit, Racer) alongside modern additions like Phantom's Revenge (a steel coaster known for a near-400 ft second drop) and Steel Curtain (part of a Steelers-themed area).

Kennywood's season runs roughly May to October, with peak crowds concentrated on summer weekends, July 4th, and during the Phantom Fright Nights event. Weekdays in June and September stay noticeably calmer. Check live queue times before committing to Phantom's Revenge or Steel Curtain, and use our crowd calendar to pick a quieter day if you want plenty of re-rides.

Six Flags St Louis

Six Flags St. Louis sits in Eureka, Missouri, 30 minutes south-west of downtown St. Louis. 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.
