Grand Marais offered a welcome harbor along Lake Superior’s exposed southern shore. Its two white steel lights gave mariners a way to recognize the entrance and, originally, a line to follow into sheltered water. The taller Inner Light still stands near Coast Guard Point, its open framework making an especially distinctive lighthouse silhouette.

History & Description
Federal harbor improvements beginning in the 1880s created a more dependable entrance to Grand Marais. Dredging and pier construction helped turn its natural anchorage into a harbor of refuge. A light and fog signal began operating at the outer end of the western pier in 1895.
A second beacon followed in 1898 at the inner end. The two formed a range: a vessel approaching on the intended course could see their lights aligned. This arrangement supplied direction as well as a recognizable harbor entrance, an important distinction along a coast where weather could quickly make shelter essential.
The Inner Light’s form is economical and purposeful. Four steel legs and diagonal braces support an enclosed workroom, gallery and lantern. Access ladders rise through the framework rather than disappearing inside a solid masonry shaft. The white finish helps the structure stand out against the trees and harbor, while its octagonal lantern gives it a familiar lighthouse crown.
A proper brick keeper’s dwelling was completed in 1908, replacing the station’s rudimentary early accommodations. The National Park Service now owns that house, and the Grand Marais Historical Society operates it as the Lightkeepers House Museum. Its domestic setting adds the human side of maintaining lamps and signals to a visit focused on the towers.
Both harbor lights remain active, although the Lighthouse Directory records that they are no longer used together as a range. The Outer Light is the lower pierhead structure; its lantern has been removed. The taller Inner Light retains its lantern, and the directory records a fifth-order Fresnel lens in service. Todd’s photographs in this gallery all show the Inner Light.

Visitor Information
- Getting there
- Follow Coast Guard Point Road to the peninsula and harbor waterfront in Grand Marais, Michigan. View the Inner Light location → This guide covers Michigan’s Grand Marais, rather than the town of the same name in Minnesota.
- Exterior views
- The Inner Light is near the keeper’s house at the shoreward end of the harbor structure. The lower Outer Light stands farther out. Shore viewpoints allow a look at the lights without committing to a pier walk.
- Tower access
- The towers are closed to visitors. Do not climb the exposed ladders or enter the workrooms.
- Keeper’s house museum
- The Grand Marais Historical Society opens the restored house seasonally, with volunteer staffing affecting availability. Its posted schedule is labeled 2024, so confirm current arrangements with the society before planning an interior visit.
- Pier conditions
- Respect posted barriers and stay ashore when waves are high or the surface is icy. Lake Superior conditions can change quickly; the exposed pier should not be treated as a safe route in every season.
- Photography
- A view from the shore shows the tower against the bay and wooded hills. From below, the steel braces and ladders provide a different composition, emphasizing the engineering that holds the lantern above the harbor.
