Wisconsin Dells

Wisconsin Dells needs 2 days: touring Noah's Ark, the largest water park in the United States with over 50 slides, on one, and riding a 'duck boat' -a WWII amphibious vehicle repurposed for tourism- through the sandstone canyon carved by the Wisconsin River, on the other. June-August brings the ideal weather for water parks, with many closing the rest of the year. It's mid-priced for the Midwest. It calls itself the 'Water Park Capital of the World,' with over 20 indoor and outdoor water parks within a few kilometers, a concentration unmatched by any other US destination.
