Michigan comprises two peninsulas. These are divided by Lake Michigan, and linked by one of the world’s longest suspension bridges across the Straits of Mackinac. Lakes Superior, Huron and Erie also form the State’s shorelines. The Lower Peninsula, mainly agricultural and industrial, contains inland lakes, meadows and sandy beaches, as well as the ‘Motor City’ of Detroit. The Upper Peninsula is more rugged, and boasts forests, white beaches, trout streams and winter ski resorts.
