Passage Island (Michigan)

Passage Island is a small island in the U.S. territory in western Lake Superior. It is the northeasternmost island in Isle Royale National Park, and the northernmost part of Michigan with any human-made structures, although the Gull Island chain is slightly further north.

The island is uninhabited, but has a lighthouse (Passage Island Light) and a short hiking trail. The U.S. National Park Service conducts tours of the island which depart from Rock Harbor on Isle Royale.
