Wildwater Kingdom is a 17-acre (6.9 ha) water park located near Cleveland in Aurora, Ohio, United States. It was built on the south side of Geauga Lake, a natural lake on the border between the city of Aurora and Bainbridge Township. Opened in 2005, it was originally part of the Geauga Lake amusement park. However, on September 21, 2007 the owners of the park (Cedar Fair Entertainment Company) announced that Geauga Lake would close and the property would operate solely as a water park beginning with the 2008 season. It is the only stand-alone outdoor water park owned by Cedar Fair outside California.
