Shaped by the currents and curves of the Wisconsin River, Wisconsin Dells has been a favorite family vacation destination for more than 150 years. An explosion of indoor water parks has turned the Dells from a summer hot spot to a year-round destination. Kids will enjoy the seemingly endless supply of fun and games, from go-karts to miniature golf, sideshows to thrill rides. If the weather's right, you can take a Duck tour of land and water, and top it all off with a heaping helping of the local fudge.
