Indiana Dunes State Park is an Indiana State Park located 47 miles (75.6 km) east of Chicago, Illinois, United States. The park is bounded by Lake Michigan to the northwest, and is surrounded in the east, south and west by the Indiana Dunes National Lakeshore, a unit of the National Park Service. The 1,530 acres (619.2 ha) Dunes Nature Preserve makes up the bulk of eastern part of the park, and includes most of the park’s hiking trails and dune landscape. This was one of the first places Richard Lieber considered when establishing the Indiana State Park system. Like all Indiana state parks, there is a fee for entrance. It was designated a National Natural Landmark in 1974.
Preserving the Indiana Dunes has resulted from the efforts of many citizens and politicians.(Wikipedia)
