"Northeast Minnesota, often referred to as "the Arrowhead" on account of its shape, is blessed with pristine wilderness, the magnificent Lake Superior, rivers, waterfalls and spectacular scenery. Miles of paved roads lead motorcyclists along the spectacular North Shore of Lake Superior, the Boundary Waters Canoe Area Wilderness, the Iron Range, the inland port of Duluth, Voyageurs National Park, and thousands of acres of national forests."
"Beginning at Canal Park in Duluth, Minnesota's North Shore Scenic Drive is a journey through an unspoiled wilderness that kisses the sweeping shoreline of the world's largest freshwater lake. The breathtaking cliffs and beaches of Lake Superior's beautiful North Shore are bordered by the Sawtooth Mountains and thousands of acres of pine, aspen and birch trees. Rivers and streams make their rocky way to the lake, forging dazzling waterfalls along the way. Lighthouses recall the awesome power of the mighty lake, and dozens of trails allow visitors to experience the North Shore's natural beauty up close. Friendly communities are home to cultural and historic museums and exhibits, as well as unique shopping, dining and lodging. You may wish to drive slowly and stop often, as the North Shore Scenic Drive reaches its destination at Grand Portage all too soon! Distance: 142 miles Travel Time: 2 hours, 40 minutes"
