North Manitou Island is managed as wilderness with the exception of a 27 acre area around the Village. Visiting the island is a primitive experience emphasizing solitude, a feeling of self-reliance and a sense of exploration. The primary visitor activities are backpacking and camping. Travel in the wilderness area is by foot only. Power on the island is provided by a photovotaic array located in the Village.
South Manitou Island is part of an island chain that extends north to the Straits of Mackinac. The island consists of a ridge of tilted layers of limestone, buried under a blanket of glacial debris. Glaciers carved out the Lake Michigan basin. When the basin filled with water, the peaks of the ridge remained exposed as islands. During post-glacial times, winds blowing on the high, sandy bluffs on the west side of the island moved sand inland, forming perched dunes. The dunes are a fragile environment. Please stay on existing paths and avoid stepping on plants.
