This Eureka amusement park opened in 1971 as Six Flags Over Mid-America and was renamed Mid America Adventure in 2026 after EPR Properties bought it and hired Enchanted Parks to run it. You get roller coasters and themed areas such as 1904 World's Fair and Chouteau's Market, and daily tickets include the Hurricane Harbor water park. In fall the park hosts Fright Fest after dark and the gentler Boo Fest.
