The water park is closed for the season. The theme park next door is open select days for Fright Fest through Nov 1, and 2027 passes that cover the water park are on sale now.
Six Flags sold the St. Louis park to EPR Properties, and Enchanted Parks runs it now. The theme park was renamed Mid America Adventure on Aug 27, 2026. The water park still goes by Hurricane Harbor, without the Six Flags name.
Hurricane Harbor is the 12-acre water park inside Mid America Adventure, formerly Six Flags St. Louis. It's drained for the winter.
For next summer, the 2027 Explorer Pass is $55.99 and covers both the theme park and the water park through Sept 6, 2027. The $75.99 Hero Pass adds free parking.
There's no public promo code for Hurricane Harbor. The water park is closed until summer, so the real deals right now are 2027 passes.
Mid America Adventure and the water park, now through Sept 6, 2027. Includes this year's Fright Fest at the theme park.

My take: if you'll swim even once next summer, the $55.99 Explorer Pass is the play. If you'll drive in and park even once, the Hero Pass comes out ahead.– John
Search "Six Flags Hurricane Harbor promo code" and you'll get generic Six Flags coupon pages. This park isn't Six Flags anymore, so those codes don't apply.

2027 water park day prices aren't out yet. Here's what a family of four pays for next summer on passes.
No. Outside food, drinks and coolers aren't allowed anywhere in Mid America Adventure, water park included. Baby food, formula and food for allergies or dietary needs are OK once Park Security or Guest Relations approves them at entry.
