If you go to the Wisconsin Dells as a tourist, you should take a ride on a DUCK. DUCKs are amphibious vehicles developed during WWII for the transport of personnel and supplies. Originally called DUKW the name morphed to DUCK for obvious reasons. There are two DUCK rides in the Dells; we took the “Original DUCK” ride which took us down the Wisconsin river, across Lake Delevan, and over some hilly terrain.
