Hawaiian Falls water parks is building an entirely new property in Roanoke, Texas which will open in 2011. The new water park will technically be owned by the city, but Hawaiian Falls will operate the park under a long term lease.
When it opens next summer, the 10 acre Hawaiian Falls Roanoke will have a large wave pool and lazy river, but also one of the largest aqua play structures in the world. Named Water World (pictured above), the structure will stand six stories tall and feature "20 slides, including a three-lane racer, a family raft ride and several body slides, 500-gallon and 1,000-gallon dump buckets, numerous interactive pulleys, wheels, and water features."
The new park should debut in May 2011, and will cost $10 million to build. Hawaiian Falls currently has three water parks in Texas. Read more about the park's development from this article.
