Marker on the map is wrong. What you want is M119, starts at Harbor Springs, goes through Good Heart, and on up through Cross Village. Follow it up to Sturgeon Bay, look at the dunes for a bit, then turn around and do it backwards.
Fun times, but it’s a 2-lane road with no center divider. It’s usually chuck full of Cyclists, so watch out for them. Also motor-homes and Sunday drivers.
