North Manitou Island is located in Lake Michigan, approximately 12 miles (19 km) west-northwest of Leland, Michigan. It is nearly eight miles long and over four miles (6 km) wide, with 20 miles (32 km) of shoreline. It has a land area of 57.876 km² (22.346 sq mi) and has no population. Smaller South Manitou Island lies to its southwest.

Both islands are in Leelanau County and are part of the Sleeping Bear Dunes National Lakeshore, although they are over 6 miles (9.7 km) offshore. Park passes and camping fees are required. The island can be accessed by a ferry service from Leland; private watercraft are permitted with limited docking. No wheeled vehicles are allowed on the island other than those used by the National Park Service or to cart off a dead deer. No campfires are allowed on the island except at public firepits near the ranger station. Similarly there is only one water spigot, and one outhouse, in the same area.
