The county is located in the state's Upper Peninsula on the shore of Lake Superior, at the southeast base of the Keweenaw Peninsula. The villages of Baraga and L'Anse are located at the base of Lake Superior's Keweenaw Bay. Point Abbaye projects north into the lake, enclosing Huron Bay. The eastern two-thirds of the county includes much of the Huron Mountains, including Mount Arvon—the highest natural point in Michigan at 1,979 feet (603 m).
