The Harbor Beach Lighthouse is located on a breakwater protecting the the harbor of Harbor Beach, Michigan. Take Michigan 25 north from Port Sanilac. In the center of Harbor Beach (you can't miss it), turn right toward the water. There is parking along the road. You can walk out on a boardwalk to get closer to the lighthouse. On a scale of 1 to 5 stars, we give it 1.5 stars. P.S. We enjoyed spending a few hours in the little stores of Harbor Beach.
