Special Events at Six Flags St. Louis

Six Flags St. Louis fans, mark your calendars! The Gateway to Thrills officially opens for the 2025 season on Saturday, April 5. Be among the first to scream with joy on the Screamin’ Eagle and take a wild spin on THE JOKER™: Carnival of Chaos featuring speeds of up to 75 MPH! Don’t forget the little ones! Keep an eye out for Bugs Bunny™ and the rest of the Looney Tunes characters as they welcome you into the park for a thrilling day!  Opening Day is just the beginning of a season full of fun, thrills and making life-long memories at one of America’s favorite amusement parks! 

A Music In The Parks festival provides a safe, fun, and educational end-of-the-year experience for school bands, orchestras and choirs.

Every Sunday in April we are making our park as quiet as possible by turning off, or turning down, as much sound as possible for the entire day.  In addition, our Guests with sensory sensitivities can enjoy a private, one-on-one character meet and greet in a low sensory setting.

Come to perform, stay for the rides!
