One of the few lighthouses that are still in operation today on the Great Lakes. It was built in 1857 under President Polk's orders to guard ships from some of the most treacherous shoals in the Great Lakes. The lighthouse is 89 feet tall with 103 cast iron steps to the top. It is owned and operated by the U.S. Coast Guard and was automated in 1957. The lighthouse has a flashing white light that shines 18 miles out over Lake Huron. It is a warning that the area contains shallow waters that can be a hazard, and it also marks the entrance into Saginaw Bay. The keeper's residence is now a museum. Tours are available Memorial Day until end of September. Call to set up your tour.
