You probably remember the commercials. Or maybe the feeling of sitting in traffic on State Route 43, staring at the massive steel tracks of Dominator or the wooden skeleton of the Big Dipper. For a hot second in the early 2000s, Aurora, Ohio, was home to the largest theme park on the planet. Not Florida. Not California. Ohio.
But if you drive past Geauga Lake today, you won’t find any 100-foot drops or Shamu shows. Most of it is just grass, a few concrete footings, and memories of a place we used to call Wildwater Kingdom. Or, if you’re a local, you just call the whole mess "the old Geauga Lake site."
Honestly, the rise and fall of this place is one of the weirdest stories in the history of the amusement industry. It’s a tale of corporate ego, a "water park war" that nobody really won, and the eventual quiet death of a landmark that had been around since 1887.
The Identity Crisis of Geauga Lake
To understand Wildwater Kingdom Ohio, you have to understand the chaos that preceded it. Before it was a standalone water park, it was part of a sprawling 700-acre mega-resort. In 2001, Six Flags did something insane: they bought the SeaWorld Ohio park right across the lake and combined it with their existing amusement park.
They called it Six Flags Worlds of Adventure.
It was massive. You could ride a hypercoaster, watch a dolphin show, and hit a wave pool all in the same afternoon. It was too big, though. The infrastructure couldn't handle it. The roads were a nightmare. The crowds were spread too thin. By 2004, Six Flags was drowning in debt and sold the whole thing to Cedar Fair—the company that owns Cedar Point—for $145 million.
Cedar Fair didn't want the animals. They shipped Shamu and the dolphins out, and they decided to turn the old SeaWorld side of the lake into a premier water park. That’s how Wildwater Kingdom was born in 2005.
What Was Actually at Wildwater Kingdom?
When it opened, it was supposed to be the "Cedar Point of water parks." They poured $26 million into the first phase alone. If you went there between 2005 and 2016, you definitely remember these spots:
- Liquid Lightning: That massive ProSlide Tornado where you'd drop 60 feet into a giant funnel. It was the centerpiece of the park.
- Thunder Falls: This was a beast. A 100-foot-tall tower with seven different slides. At the time, it was the tallest water slide complex in Ohio.
- Tidal Wave Bay: A 390,000-gallon wave pool that produced four-foot waves.
- Splash Landing: The four-story "family play area" with the giant 1,000-gallon bucket that dumped water on everyone every few minutes.
For a few years, it felt like it might actually work. But there was a glaring problem. Across the lake, the "dry" ride side—the historic Geauga Lake park—was struggling. Attendance was cratering.

In September 2007, Cedar Fair dropped a bomb. They announced that the amusement park side would close forever. Just like that. The roller coasters were dismantled, sold, or scrapped. Dominator went to Kings Dominion. X-Flight went to Kings Island.
Wildwater Kingdom was left as a "standalone" park. It was basically an island of water slides in a sea of abandoned roller coaster footings.
Why Did It Close?
People always ask why Cedar Fair would kill a park that had survived for over a century. There are a few theories. Some folks think Cedar Fair only bought it to eliminate the competition for Cedar Point, which is only about 80 minutes away. Others say the local government in Aurora and Bainbridge made it too hard to expand.
The truth is probably simpler: money.
Operating a seasonal water park in Northeast Ohio is a tough gig. You have maybe 90 days of good weather if you're lucky. By the time 2016 rolled around, attendance had dipped significantly. The "wow" factor of being part of a giant resort was gone. On September 5, 2016, Wildwater Kingdom let the last guests through the gate and locked up for good.
What’s Happening at the Site Right Now (2026 Update)
If you’re looking for a nostalgia trip, you might be surprised to see what’s actually happening there this year. For a long time, the land just sat there. It was creepy. Urban explorers would sneak in to take photos of the rotting slides and the empty Big Dipper station.
But as of early 2026, the "Aurora Park at Geauga Lake" project is finally taking real shape.
The City of Aurora bought about 48 acres of the lakefront property (the old SeaWorld/Wildwater Kingdom side). They aren't building a new theme park, but they are turning it into a massive public recreational space. Here is the current status of the redevelopment:

- Phase 1A Completion: Most of the initial site work, including the renovation of the old gatehouses into open-air pavilions, is wrapping up right now.
- The Beach and Pool: Construction is underway for a new public pool and beach area. The goal is to return the lake to its 19th-century roots as a place for swimming and boating.
- Residential Growth: The land that isn't part of the public park is being filled with hundreds of new homes and apartments. It's essentially becoming a high-end lakeside neighborhood.
Common Misconceptions
You'll see people online calling it "White Water Kingdom" all the time. Technically, the name was Wildwater Kingdom. The "WhiteWater" name actually comes from WhiteWater West, the company that manufactured many of the slides. It’s an easy mistake to make, especially since the two names are so similar and "white water" describes the rapids in a lazy river.
Another myth? That the Big Dipper is still standing. It’s not. The historic wooden coaster was finally demolished in late 2016 after years of decay. It was a heartbreaking sight for anyone who grew up in the Cleveland or Akron area.
Actionable Steps for the Nostalgic
If you want to relive the glory days of Wildwater Kingdom Ohio or see what’s left, you can’t just walk onto the property—much of it is now private construction or residential. However, here is how you can still engage with the history:
- Visit the New Aurora Park: Once the first phase officially opens to the public later this year, you’ll be able to stand on the same shoreline where the SeaWorld stadium once stood. Bring a kayak; the new launch will be the best way to see the lake.
- Check the Geauga Lake Historical Society: They have an incredible archive of photos and memorabilia from the park's transition from a trolley park to a Six Flags giant to a water park.
- Ride the Survivors: If you miss the rides, go to Kings Dominion in Virginia to ride Dominator, or head to Michigan’s Adventure to ride Shivering Timbers’ cousin (built by the same designers). Many of the old Geauga Lake rides are still operating under different names in other Cedar Fair parks.
The era of massive, multi-park resorts in Aurora is over, but the land is finally becoming something the community can use again. It’s not a 100-foot water slide, but a public beach on the lake is a lot better than a fenced-off field of weeds.
