It was established in 1887, in what had been a local recreation area adjacent to a lake of the same name. The first amusement ride was added in 1889, and the park's first roller coaster – the Big Dipper – was built in 1925. The park was sold to Funtime, Inc., in 1969 and was expanded over the years with additional rides and amenities. Funtime was acquired by Premier Parks in 1995, and for the 2000 season, they re-branded Geauga Lake as Six Flags Ohio, adding four new roller coasters. The following year, Six Flags bought the adjacent SeaWorld Ohio and combined the two parks under the name Six Flags Worlds of Adventure.
