This awesome water park's half-million square feet of indoor and outdoor space adds up to 12 football fields of wet and wild family fun. On balmy days, enjoy the slides, rivers and waterfalls of New Frontier Waterpark. But the fun doesn't stop in winter thanks to the all-season Wild WaterDome, where guests can sun themselves year round. "The Wilderness Resort is the perfect cabin-fever reliever for those seemingly endless Midwestern winters," says park fan Kara Ashenhurst.
