Big Rivers Halloween is a seasonal Halloween event taking over Big Rivers Waterpark throughout October and November 1. The park transforms with Halloween attractions, activities, entertainment, trick-or-treating, seasonal decor, photo opportunities, and more.

The event features two distinct experiences: Boo Rivers, a family-friendly Halloween celebration, and Voodoo Bayou, a darker and scarier experience geared toward guests looking for more of a thrill. Admission includes access to both areas, so guests can choose how spooky they want their night to be.
