Situated roughly 45 miles southeast of Niagara Falls, this 10-acre water park is part of the Darien Lake amusement park complex, which has entertained families seasonally for more than 50 years. Splashtown offers seven slides, such as the 70-foot-tall Brain Drain and 700-foot-long Big Kahuna. In addition to slides, visitors can float in the heated lazy river, play in the pirate-themed water playground and splash around in the 600,000-gallon wave pool. The property also features a hotel, cabins and campsites.
