Located within Pictured Rocks National Lakeshore, this picturesque lighthouse stands on Au Sable Point on the south shore of Lake Superior, approximately 12 miles west of Grand Marais, Michigan. 

Built in 1873-1874, the light tower's base diameter is 16 feet with a height of 86 feet. The tower extends 23 feet underground and is anchored in bedrock. A brick oil building and fog signal building were built in the 1890s. All of the buildings on site, along with the tower and keepers' quarters, make up the light station

The original keepers' dwelling was attached to the light tower in the back. In 1909, a new residence was built for the head keeper and the existing building expanded so it could accommodate two assistant keepers and their families. One family lived upstairs and one downstairs, with separate entrances. In 1945 the U.S. Coast Guard took over, replacing the civilian keepers. In total, the light station was continually staffed for 84 years, until the Coast Guard left in 1958.

A third-order Fresnel lens reflected the first light, which was fueled initially by lard oil and then by kerosene. The fixed white beam could be seen 17 miles out on the lake. The lighthouse became fully automated in 1958 and transferred from the Coast Guard to the National Park Service in 1968. The lighthouse still operates - a smaller, solar-powered light now sits on the catwalk railing and shines over Lake Superior every evening.


Visiting the Au Sable Light Station
To visit the Au Sable Light Station, drive to the lower Hurricane River Campground located 12 miles west of Grand Marais on Alger County Road H-58. Park in the day-use area. 

It is a 1.5 mile walk (one way) to the lighthouse. From the day-use parking lot, walk east through the campground from the picnic area near the Hurricane River mouth. The trail continues past the campground on the historic U.S. Coast Guard access road to the light station. Be alert for occasional staff vehicle traffic.

On the beach below the trail, exposed shipwreck remains dot the shoreline. Watch for the signs and steps to the beach along the access road. Drinking water and a toilet are available seasonally at the light station. Leashed pets are permitted on the access road to the light station and on the station grounds, but not in the buildings. Bicycles are not permitted on this road.

NOTE: On hot, humid days in summer with a south wind, biting flies in this area can be fierce and can ruin your visit to the light station. Consider wearing loose-fitting long pants and socks before starting down the trail.
