Most visitors to this town of 2,700 spend time twisting down water slides or floating in wave pools. What almost certainly ranks as one of the most kid-friendly vacation spots in the Heartland revolves around giant indoor and outdoor water parks, such as Mount Olympus (pictured).
But be sure to see the Dells, the unique, craggy bluffs rising over the Wisconsin River like stacks of sandstone pancakes. Some of the best views are from double-decker excursion boats. And attractions in nearby Baraboo, including Circus World Museum and the International Crane Foundation, are worth leaving the pool for as well.

A trip to the Dells means you're only minutes away from this Baraboo animal habitat, the one place in the world where all 15 species of cranes live. Take guided or self-guided tours through savanna and tallgrass prairie, see whooping cranes in a wetland and learn about preservation efforts. (608) 356-9462; savingcranes.org
