Wisconsin Dells is a city in south-central Wisconsin, with a population of 2,678 people as of the 2010 census. It straddles four counties: Adams, Columbia, Juneau, and Sauk. The city takes its name from the Dells of the Wisconsin River, a scenic, glacially formed gorge that features striking sandstone formations along the banks of the Wisconsin River. Together with the nearby village of Lake Delton, the city forms an area known as "the Dells", a popular Midwestern tourist destination.
