Silver Cliff is the highest bluff rising out of Lake Superior. In 1923 builders carved Highway 61 out of the cliffside 125 feet above the lake. In 1994, after three years of blasting and the removal of a million cubic yards of rock, the tunnel was completed as a safer route. To walk the old route, park at the wayside rest on the northeast side of the tunnel and walk the half-mile paved path that follows the old highway bed at cliff’s edge. Take in the wide open views of Lake Superior.
