Commonly confused with the Big Sable Point Light of Ludington and the Little Sable Point Light of Pentwater is the Au Sable Light in Grand Marais, Michigan. This active lighthouse has been in operation sin 1874, soon after the structure was completed.

Located on what is known once as Lake Superior’s shipwreck coast, the Au Sable Light Station has been guiding ships through the shallow ridge of Au Sable Point reef. The area has always been a ship trap, which is why it is extremely important to light it.

Today, the Au Sable Light is open to the public every summer. It is under the care of the National Park Service that maintains the place in its 1910 appearance. The US Coast Guard still maintains it as a navigation aid as well.
