Indiana Dunes State Park occupies the south shore of Lake Michigan east of Chicago and forms a central preserved section of the Indiana Dunes. Established in 1925 as part of Indiana’s early state park system, it protects a dynamic landscape created as Lake Michigan retreated after the Ice Age, leaving shifting dunes, blowouts, marsh, forest, and exposed remnants of older terrain. Its eastern section includes the 1,530-acre Dunes Nature Preserve, recognized as a National Natural Landmark in 1974, with features such as Big Blowout, the Tree Graveyard, the Tremont dunes, and the Ancient Pines Nature Area. The park remains heavily visited for beaches, hiking, birding, camping, and scenic views.
