Kalahari Resort, Wisconsin

This 125,000-square-foot Wisconsin Dells indoor water park is the largest in the state (and that’s saying something for an area that is overflowing with water parks). Float down the 920-foot lazy river or take the whole family on the Victoria Falls waterslide, a 504-foot group raft ride. Later, adults can grab a drink at the park’s swim-up bar while kids play a game of water basketball in Crocodile Cove.

Take a break from skiing the slopes at Jay Peak and relax in the park’s indoor and outdoor hot tubs — you can even watch the snow fall while you sit in 100-degree-plus water.

Inside is an oasis of real plants (no plastic here!), two lazy rivers, body slides, coves designed for small children, and, in true Nashville fashion, an area just for adults.
