Best Water Parks in Southern Utah for Kids

When Southern Utah turns into an oven (looking at you, July), there are two types of parents: the ones pretending it’s “not that hot,” and the ones already loading towels into the car. If you’re in the second group, here are some of the best water parks and splash spots around Southern Utah that are actually worth the sunscreen battle.

If your kids have energy to burn (and they always do), this floating inflatable water park at Quail Creek is basically a giant playground on water.

Obstacle courses, trampolines, and slides
Swing jumps into the reservoir
Chill areas for parents who “just want to supervise” (aka sit)

It’s one of the most unique water experiences in Southern Utah and surprisingly affordable, usually around $12–$17 per person.
