Summer in Cincinnati and Dayton gets hot, humid and long, and the neighborhood pool can only entertain kids for so many afternoons. The good news is that some of the best outdoor waterparks in the Midwest sit within a few hours of southwest Ohio, and several of them are legitimately ranked among the best in the country. Here’s where to go, how far you’ll drive, and what makes each one worth the gas money.
Kings Island’s Soak City: Mason, OH (25-30 minutes)
If you want a big-league waterpark without leaving the metro, Soak City is the obvious pick. It’s included with Kings Island admission and packs more than 50 water activities, including 36 water slides wate across its grounds, along with tropical-themed lagoons, rushing rivers and surfable waves. There are two wave pools to choose from, plus a lazy river for the “I just want to float” crowd. The park has also been expanding in recent years, so it’s worth checking even if you haven’t been in a couple of years. Because it’s bundled with the amusement park, it’s the easiest option for a spontaneous day trip.
Hurricane Bay at Kentucky Kingdom: Louisville, KY (1.5-2 hours)
Hurricane Bay has serious bragging rights. It’s included with Kentucky Kingdom admission and spans six acres, with two large wave pools, a lazy river called Castaway Creek and a swifter-moving Adventure River. The signature ride is Deluge, a hydromagnetic rocket slide that launches riders up and down hills, and there’s a dedicated toddler area plus a multi-level interactive water playground for younger kids. Louisville is close enough for a day trip but far enough to feel like a real getaway.
Splashin’ Safari at Holiday World: Santa Claus, IN (2.5-3 hours)
This is the one to plan a whole weekend around. Splashin’ Safari is consistently ranked among the top water parks in the country and is known for its water coasters. Wildebeest and Mammoth are two of the longest water coasters in the world, and Cheetah Chase lets racers duel side by side. On top of the coasters, guests get two wave pools, a lazy river and a full lineup of family slides. Since Holiday World and Splashin’ Safari share one admission, you also get a full theme park as part of the trip, including The Voyage, one of the top-rated wooden coasters in the world.
Zoombezi Bay: Powell, OH (1.5-2 hours)
Attached to the Columbus Zoo, Zoombezi Bay is one of the largest waterpark destinations in the state. It’s a four-acre water attraction with both indoor and outdoor areas, featuring, a lazy and rapid river, a wave pool, multi-level play structures and adult-only pools. The indoor component means a rainy afternoon doesn’t necessarily sink the trip, and because it’s paired with the zoo, it’s an easy two-in-one outing if you’re making the drive up I-71 anyway.
Cedar Point Shores: Sandusky, OH (3.5-4 hours)
This is the farthest drive on the list, but it’s the one to build a whole trip around if your family leans toward thrill rides. Cedar Point Shores sits right on Lake Erie next to Cedar Point amusement park and spans 18 acres. The centerpiece is Breakwater Bay, a half-million-gallon wave pool, and there are two lazy rivers: Cedar Creek for a slower float and Runaway Rapids, which runs guests past waterfalls and geysers. Thrill-seekers should head straight for Point Plummet, a six-story capsule drop slide that opens onto a near-vertical fall, plus a handful of enclosed and open-air slide complexes for older kids. Younger kids get their own shallow-water play areas with mini slides and spray features. Because of the drive, this one pairs best with an overnight stay, and it’s easy to turn into a two-day trip since Cedar Point’s roller coasters are right next door.
Worth Knowing Before You Go
- Check hours before you leave. Waterparks close for weather and staffing shortages more often than typical attractions, and most switch to weekend-only hours in late August.
- Kings Island, Holiday World and Cedar Point all bundle water park and theme park admission, so budget a full day (or two) if you want to do both.
- Louisville, Santa Claus and Sandusky trips all pair well with an overnight stay. Starting the next morning at the park beats a long drive home after a full day in the sun.
- The Beach Waterpark in Mason, once a Cincinnati staple, is permanently closed and has been since 2019, so don’t plan a trip around it.
- If you’re not up for the drive, Cincinnati splash pads and Dayton splash pads are a solid closer-to-home alternative.
