Six Flags St. Louis is Mid America Adventure now.
The park site has it up this morning: today Six Flags St. Louis officially becomes Mid America Adventure. New name, new logo. First Alert 4 (KMOV) and Attractions Magazine both have the Thursday drop, and Enchanted Parks already lists the park under the new name.
Enchanted Parks bought the Eureka park (and a handful of other former Six Flags parks) back in March 2026. Park president Danny Snider told KMOV they are rolling out the new name so families keep getting safe, clean fun visits and lasting memories there. Enchanted Parks CEO James Harhi called the rebrand the next step in investing in the park and the community.
Rides stay. Hurricane Harbor stays. 2027 season passes are on sale for $75 and work for the rest of 2026 too (including Fright Fest), per KMOV. Attractions Mag also notes 2026 tickets you already bought still work, and Six Flags season passes / memberships bought before April 6, 2026 keep their 2026 benefits.
