SplashTown is a water park located north of Houston in the Spring CDP of unincorporated Harris County, Texas, United States.
In the Early-1980s, the land that Splashtown now occupies was another theme park known as Hanna-Barbera Land. Splashtown purchased the land and converted it into a water park facility. The original name was "Splashtown USA" but the "USA" was dropped after the first year. Around the same time as Splashtown USA opened, another park Splashtown San Antonio was also opened. Some people incorrectly assume these two parks are related or owned by the same company. They were owned by the same limited partnership until 1994 when SplashTown Houston was purchased by the Morris Family. The park was sold to Six Flags in May of 1999. Incredibly, Six Flags bought the park without ever touring or inspecting it.
