Six Flags St. Louis has entertained Midwest thrill-seekers from its home in Eureka, Missouri, since June 5, 1971, when it opened as Six Flags Over Mid-America. Spread across roughly 323 acres in the Ozark foothills southwest of downtown St. Louis, the park pairs about 10 roller coasters with family rides, live shows, and the adjoining Six Flags Hurricane Harbor water park.
The park’s signature attraction, Screamin’ Eagle, debuted in 1976 as a Bicentennial showpiece and was certified by Guinness World Records as the tallest and fastest wooden coaster on Earth at the time. Decades later, the wooden classic still anchors a coaster lineup that ranges from the inverted loops of Batman: The Ride to the launched thrills of Mr. Freeze: Reverse Blast, making Six Flags St. Louis one of the busiest seasonal parks in the Midwest.

The Ride Experience

Steel thrills come from Batman: The Ride, a Bolliger & Mabillard inverted coaster, and Mr. Freeze: Reverse Blast, a Premier Rides launch coaster that fires riders forward and backward through a twisting steel track.

A Park with Deep Missouri Roots
The park opened in 1971 as Six Flags Over Mid-America, one of the earliest Six Flags-branded parks outside Texas, before being renamed Six Flags St. Louis in 1996. It expanded with the Six Flags Hurricane Harbor water park in 1999 and added seasonal events such as Fright Fest over the following decades.
In 2026, Six Flags sold the property to EPR Properties as part of a seven-park deal, shifting day-to-day operation to a new company called Enchanted Parks, which has said it plans to rename the park Mid-America by Enchanted Parks in a nod to its original 1971 name.
