Lake Superior is a lake in central North America that straddles the Canada–United States border, with the U.S. state of Wisconsin located along its southern shore. It is the largest freshwater lake in the world by surface area and the third largest by volume, holding 3 quadrillion gallons of fresh water. Wisconsin’s Lake Superior Scenic Byway follows the southern shoreline along the Bayfield Peninsula, highlighting the geological, historical, cultural, ecological, and recreational diversity of the region, including scenic views of forests, sandy beaches, and landmarks like the Apostle Islands National Lakeshore and the Gaylord Nelson Wilderness Area.
