Was very pretty! Definitely would do it again.
If you're into going for a nice drive, try this road once. It has a mixture of higher speed, straighter sections, as well as tight, winding, slower sections. Wonderful road.
I am not a geologist to understand the creation of the moraine but I do know beauty and this is a beautiful drive. Take your time, it is very curvy.
I drove the section farther north near the west side of Sheboygan County. I lived along Lake Michigan for many years so I had plenty of time to have a drive through the Kettle Moraine. It is wonderful to drive through during the fall months late September through November. Most of the roads are very twisty and covered on both sides by thick woods. Definitely a wonderful Sunday drive!
