Mt. Olympus Water and Theme Park is a theme park and water park complex in Wisconsin Dells, Wisconsin. Mt. Olympus consists of four areas of the park: Zeus' Playground (outdoor theme park), Neptune's Water Kingdom (outdoor waterpark), The Parthenon, and Medusa's indoor water park. In 2010 and 2011, the park purchased several smaller nearby independent motels and hotels and renamed them, painting them blue and white to fit the Greek theme for the main hotel.
