Hawaiian Falls is a small chain of seasonal Texas water parks with slides, wave pools, lazy rivers and children's play areas, with parks currently operating in Mansfield, Roanoke and Waco. Ripley Entertainment, the company behind Ripley's Believe It or Not, acquired the three parks in August 2025 and is investing more than one million dollars in upgrades, including refreshed rides and expanded shade, ahead of the 2026 season opening on May 2. The Mansfield location sits in the Dallas-Fort Worth area and, like the other parks, typically runs from Memorial Day weekend through Labor Day.
