Thunder Bay Island Light

Thunder Bay Island Light is a brick tower located on an island in Lake Huron off the coast of Michigan's Upper Peninsula. The compound includes the main tower, attached living quarters for the keeper, and a separate building that housed fog signal equipment.

An early attempt to build a lighthouse on the island failed, but a new tower was successfully constructed in 1832 to warn ships of dangerous reefs in the area. The structure became essential for safe navigation along this challenging stretch of Lake Huron.

The lighthouse station served as a focal point for the fishing families who made their homes on and around the island during the 1800s. The structures still reflect the close connection between the community and maritime life that defined this place for generations.

The island is protected and public access is limited to support ongoing restoration work. Check ahead before planning a visit, as preservation activities may affect when and how you can explore the site.

The island provides important nesting habitat for several seabird species including ring-billed gulls, common terns, and herring gulls. The lack of predators makes it an ideal breeding ground where bird populations thrive throughout the year.
