Water World is a water park that is part of the Hyland Hills Park and Recreation District and located in Federal Heights, Colorado, roughly 10 miles (16 km) north of downtown Denver, Colorado. The park first opened in 1979 and is generally open from Memorial Day through Labor Day, but may be closed some school days.
The park occupies 67 acres (27 ha), making it one of the largest water parks in the U.S. in terms of acreage, and as of the 2008 season, has over 44 attractions including a multitude of water slides, a "lazy river" (a circular artificial river with a slow moving current), inflatable tube rides, multi-passenger inflatable raft rides, and a water-themed fun house. The park has two wave pools: the older and tamer Captain Jack's Wave Pool, as well as the newer Thunder Bay wave pool, which as of the 2009 season, has longer continuous waves that start every six minutes. It formerly had one large wave every four minutes.
