Lake Michigan is one of the five Great Lakes of North America, and the only one located entirely within the United States. It is the second-largest of the Great Lakes by volume and the third-largest by surface area. Lake Michigan is shared, from west to east, by the U.S. states of Wisconsin, Illinois, Indiana, and Michigan. Lake Michigan is home to the largest dune system in the world associated with a freshwater lake. Notable parks include Silver Lake Sand Dunes, Arcadia Dunes, Sleeping Bear Dunes, and Indiana Dunes National Lakeshore. Indiana Dunes National Park is on the southern shore of Lake Michigan in Indiana. It has a string of sandy beaches, and trails through dunes, marshland, and jack pine forests. The Dune Succession Trail at West Beach has views of the Chicago skyline and the lake’s bird-rich wetland.
