Wild Slides, Lazy Rides & Endless Family Fun

Slip, slide and splash into fun at Jolly Mon Indoor Water Park. This 20,000-square-foot water park features 600 feet of twisting slides, a lazy river, an oversized whirlpool and an action-packed activity pool. Climb the three-story wilderness treehouse, dodge water blasters and brace for the 600-gallon tipping bucket. Whether you’re floating or free-falling, every splash is a good time. Refuel at the Snack Shack and celebrate in our private party rooms.
