Raging Waves Waterpark
At Raging Waves Waterpark, Illinois' largest water park, certified lifeguards keep a vigilant watch over visitors as they traverse a park filled with 20 water slides and other aquatic attractions, but surveillance isn’t their only job. They secure up to four passengers in tubes before they zoom down a giant family slide and instruct riders on how to position their arms during their plunge down a winding speed slide with a near-vertical drop. Though adrenaline is the Raging Waves' main focus, it also houses slower-paced attractions for the entire family such as a wave pool, a quarter-mile lazy river, and two separate children's play areas.
