15 Best Indoor Water Parks in the U.S.

"Spending a day at the pool doesn't have to depend on good weather. Conveniently sheltering their attractions from the elements, the best indoor water parks in the U.S. are perpetually toasty escapes in rain or shine, any time of the year. Simply pack a swimsuit on your next trip to Vermont, New Hampshire, Wisconsin, or Pennsylvania, regardless of the forecast."

"Speed down Medusa's Slidewheel-the first rotating waterslide in the U.S.-at up to 25 miles per hour, occasionally catching air. With both indoor and outdoor water parks, Mt. Olympus is also home to the country's tallest waterslide, The Rise of Icarus, which swirls down from a 145-foot platform. However, since it's outside, you can only brave it between mid-May and mid-September."

Indoor water parks across multiple U.S. states offer year-round, climate-controlled aquatic recreation that does not depend on weather. Facilities range from hotels with glass-domed slides and pools to ski-resort surf simulators and adults-only zones. Mt. Olympus in Wisconsin features Medusa's Slidewheel, the first rotating waterslide in the U.S., and hosts the outdoor 145-foot Rise of Icarus during summer months. Tropic Falls at Owa in Alabama includes 75-foot slides, a wave pool, a surf simulator, a retractable glass roof, and 23 attractions. DreamWorks Water Park in New Jersey uses a glass dome to fill the space with natural light and extensive ride options.
