Southern Utah might be famous for its red rocks, national parks, and endless hiking trails—but when the desert heat kicks in, there’s nothing better than cooling off at a water park. Whether you’re a local looking for a weekend splash or a traveler searching for the perfect family stop, there are some amazing options to explore.
In this post, we’re ranking the top 5 water parks in Southern Utah — and showing you exactly why Jellystone Park near Zion stands above the rest.
5. Hidden Valley Park
A Neighborhood Oasis
Located in St. George, Hidden Valley Park is a community favorite that features a simple but fun splash pad, along with a shaded playground and open grassy areas. It’s a great low-key option for families with young kids or locals who want to stay close to home.
However, it’s more of a park with water features than a full-on water park. If you’re looking for slides, a pool, or resort vibes — you’ll want to look further down this list.
4. Thunder Junction
Fun for Everyone
Thunder Junction All Abilities Park is one of St. George’s most inclusive play spaces, and that includes a small splash area. What makes this park special is its accessibility—it’s designed so kids of all abilities can play, splash, and explore safely.
While it’s not a traditional water park, its thoughtful design and free access make it a great community asset. If you’re traveling with children who have special needs, this is definitely worth a visit.
3. St. George City Pool
Public Fun with Water Slides
For a more classic water park vibe, the St. George City Pool offers water slides, diving boards, a lazy river, and a zero-depth entry play area for little ones. It’s a public facility, so pricing is affordable, and it tends to be busiest during summer weekends.
2. Sand Hollow Aquatic Center
Indoor Water Fun
Need to beat the heat or the weather? Sand Hollow Aquatic Center is an indoor water park that features multiple pools, splash zones, and a few slides. It’s great for year-round swimming and provides a reliable experience no matter what the forecast holds.
That said, the indoor setting can’t match the open-air thrill of a resort-style park, and it’s more functional than adventurous. Still, it’s a family favorite in the region.

Topping the list is Jellystone Park near Zion National Park, and it’s not even close.
This isn’t just a water park—it’s a full-on vacation experience. With a giant splash zone, thrilling water slides, a lazy river, and plenty of shaded seating and cabanas, Jellystone brings a resort-level water experience to the heart of Southern Utah.
