From the website....The Indiana Dunes State Park consists of 2,182 acres of primitive, beautiful, historical, and amazingly unique Hoosier landscape. It lies in Porter County and includes more than three miles of Lake Michigan's south shore, all of which provides a magnificent beach. Eighteen hundred acres are wooded and contain the most diversified flora and fauna of the Midwest.
