SeaWorld Ohio was a marine zoological park and theme park located in Aurora, Ohio, managed and owned by Busch Entertainment Corporation. As the second installment after SeaWorld San Diego, it was created by George Millay, the original founder of the SeaWorld franchise. After being acquired by Six Flags, it combined with the neighboring Geauga Lake to form Six Flags Worlds of Adventure. Subsequently, under Cedar Fair's ownership, the location was transformed into the water park Wildwater Kingdom (Ohio), which remained operational until its closure in 2016.
SeaWorld Cleveland (1970–2000)
In 1966, Earl Gascoigne, then marketing director at Cedar Point in Sandusky, Ohio, approached George Millay with a proposal to establish a second SeaWorld park near Ohio; however, Millay initially declined. By 1968, Millay planned to expand eastward, targeting the densely populated area between Detroit and Pittsburgh. At that time, Gascoigne was redeveloping Geauga Lake close to Cleveland and persuaded Millay to site the new SeaWorld adjacent to Geauga Lake to enhance visitor numbers and profitability.
SeaWorld Cleveland, initially named Sea World of Ohio, opened on May 29, 1970, occupying 25 acres in Aurora, Ohio. The $5.5 million oceanarium surpassed expectations with an opening day attendance exceeding 5,500 guests and over 1.1 million visitors during its first season. The park received accolades for its landscaping and design quality. By 2000, SeaWorld Ohio had expanded to cover 232 acres but faced limitations on introducing roller coasters or water rides due to a non-compete clause with neighboring Geauga Lake.
Six Flags Worlds of Adventure (2001–2003)
On January 10, 2001, Six Flags purchased SeaWorld Ohio from Busch Entertainment Corporation for $110 million, merging it with the adjacent 520-acre Six Flags Ohio (previously Geauga Lake) along with nearby campgrounds and hotels. The acquisition was motivated partly by growth restrictions imposed on SeaWorld Cleveland under Busch's ownership.
Following the merger in 2001, the combined properties were rebranded as Six Flags Worlds of Adventure, encompassing 750 acres. The resort was segmented into three distinct zones: Wild Life (formerly SeaWorld), Wild Rides (Geauga Lake), and Wild Slides (a 10-acre water park), all accessible with a single admission ticket. The transaction excluded orcas and dolphins; consequently, the orca show was replaced by dolphins sourced from Six Flags Discovery Kingdom until a new orca arrived on loan from France. Six Flags introduced family-friendly rides and a Batman-themed water ski performance. President Gary Story announced a five-year development plan featuring attractions such as a submarine ride, volcano experience, rainforest exhibit, and a monorail system.
Six Flags Ohio attracted 1.7 million visitors in 2000; attendance increased to 2.7 million in 2001 post-merger but fell short of the anticipated 3 million.
Geauga Lake & Wildwater Kingdom (2005–2007)
Cedar Fair acquired the entire Six Flags Worlds of Adventure property on March 10, 2004, for $145 million; however, the animal collection remained with Six Flags. This divestiture allowed Six Flags to reduce debt and concentrate on other operations across North America.
In 2004, Cedar Fair reopened the site as Geauga Lake without any animal exhibits and restricted access to areas formerly occupied by SeaWorld attractions. All Six Flags branding elements—including DC Comics and Looney Tunes themes—were removed due to licensing constraints.
On June 17, 2005, Cedar Fair unveiled Wildwater Kingdom, a new 17-acre water park situated on the former SeaWorld grounds, leading to a rebranding as Geauga Lake & Wildwater Kingdom. Although initially planning a $24 million expansion in 2006, this was scaled down to include only a $5 million wave pool addition. This water park aimed to offset the loss of marine-themed attractions; many marine structures were dismantled or repurposed.
Attendance declined dramatically under Cedar Fair’s management—from 2.7 million visitors in 2001 to approximately 700,000 in 2004—and remained stable through 2006. After the conclusion of the 2006 season, Cedar Fair removed major attractions such as X-Flight and Steel Venom roller coasters and shortened the operating season to just 101 days while discontinuing Halloween events altogether.
Wildwater Kingdom (2008–2016)
On September 21, 2007, Cedar Fair revealed that for the 2008 season, Geauga Lake & Wildwater Kingdom would transition to operate exclusively as a waterpark. At the time, Cedar Fair CEO Dick Kinzel highlighted that Wildwater Kingdom was the park’s most favored attraction. The organization sought to better cater to the regional audience by focusing solely on the waterpark experience.
Cedar Fair announced on August 19, 2016, that Wildwater Kingdom would remain closed for the 2017 season and beyond. After eleven years of operation, the waterpark permanently ceased operations on September 5, 2016. Demolition activities commenced in November 2017. By August 2020, redevelopment efforts began on the location, aiming to create a mixed-use development comprising 308 residential units, 20 acres dedicated to commercial use, and 98 acres of green parkland.
Attractions
SeaWorld Ohio offered a diverse range of rides, animal displays, and live entertainment.
Rides and attractions
Following SeaWorld’s purchase of the Aurora property in 1970, an agreement with Geauga Lake imposed restrictions preventing SeaWorld from adding roller coasters or water attractions. Conversely, Geauga Lake was barred from introducing animal exhibits. Consequently, SeaWorld emphasized theaters and motion-simulator experiences over conventional rides, complemented by playground areas throughout the park.
