Manitou Island is a small island in Lake Superior, off the northeastern tip of the Keweenaw Peninsula in the U.S. state of Michigan. It is part of Grant Township, in Keweenaw County. Located approximately three miles from the mainland, it encompasses around 1,000 acres (4.0 km2). Manitou has seen limited impact from human activity because of its remote location and the often-treacherous waters caused by a strong current at the peninsula's tip. It is mostly forested, with scattered bogs and an inland lake known as "Perch Lake". Dense underbrush can make travel around the island rather difficult, though a few unimproved trails do exist. The Keweenaw Land Trust protects 93 acres (0.38 km2) of the island as the Manitou Island Light Station Preserve.
