The visual experience of traveling along the Wisconsin Great River Road is why the entire 250-mile route was voted Prettiest Drive: Ultimate Summer Road Trip In The United States. The Mississippi River and its backwaters flanked by sandstone bluffs standing over 500 feet tall with the Great River Road winding between make for scenic opportunities around every curve. Sand prairies offer expansive views. River valleys from the many rivers of Wisconsin feeding into the Mississippi River offer beautiful views. The Great River Road runs through the Driftless Area from where the Chippewa River joins the Mississippi River down to the border with Illinois. This area is known mainly for its deep carved river valleys and remain today for our viewing pleasure because it was not covered by glaciers during the last ice age.
