This water park is one of the largest in the U.S. with more than 49 different attractions on 64 acres. The star attraction is the Mile High Flyer, a fast-flying water coaster. But The Storm is also a nail biter: The raft ride zooms thrill seekers through a dark tube that recreates a storm with loud thunder, flashes of lightening and rain. The park also has an exhausting selection of wave pool, tube slides, and splash-down rides for the entire family. Day tickets run $39 (adults) and $33 (children).
