Added to the National Park System as a national "lakeshore," back in 1966, Indiana Dunes National Lakeshore in Indiana is now a national park as of 2019. This was not a sudden decision, but rather a decision that took a long time to bring to fruition.

Located on the southern shore of Lake Michigan, this unit of the park system includes some of the most geologically and biologically diverse areas in the United States. The “Indiana Dunes” were formed over a period of 12,000 years by natural forces, including glaciers, wind, and water. Native American tribes, including the Miami and Potawatomi Indian tribes, inhabited the Indiana Dunes region for over 10,000 years.

More recent additions -- an 1822 homestead, 1900s family farm, and houses originally exhibited at the 1933 Chicago World’s Fair -- also can be found at Indiana Dunes. 

Legislation calling for the name change noted that "local conservation efforts to preserve the Indiana Dunes began as early as 1899 when Henry Cowles, a botanist from the University of Chicago who is known for being one of the founders of contemporary ecological study and thought, published an article entitled 'Ecological Relations of the Vegetation on Sand Dunes of Lake Michigan' in the Botanical Gazette, bringing international attention to the intricate ecosystems on the Indiana Dunes. On October 30, 1916, 1 month after the establishment of the National Park Service, Stephen Mather, the first director of the National Park Service, held hearings in Chicago, Illinois, to gauge public sentiment on establishing a large portion of the southern shore of Lake Michigan as one of the first national parks in the United States, to be known as the 'Sand Dunes National Park.'"

However, Mather's plans were interrupted because the United States entered World War I and national focus shifted away from national parks to national defense.

Getting to this national park is easy, since it’s in a very urban region of the state, right next to Illinois and two large airports (Chicago O’Hare and Chicago Midway) between 1 – 1.5 hours drive time away. Arrive at the South Bend International Airport and the trip is under an hour. Regardless of the direction taken, Indiana Dunes National Park is a great side trip for a day outdoors.

Despite the crowding of the surrounding urban environment, Indiana Dunes is a rich ecological island. Though it covers just 15 miles of Lake Michigan beachfront, and 15,000 acres overall, the biological diversity here is among the highest in the National Park System.

Pinhook Bog, for example, is Indiana's only true bog. Here a layer of sphagnum moss floats atop an ancient lake and serves as the rooting medium for a forest. The Cowles Bog Complex is a mix of wetlands that is a small remnant of an area known as the Great Marsh, where an open body of water flowed into Lake Michigan 4,000 years ago. The bog is being restored with native plants with a goal to boost the lakeshore's biological diversity, provide a resting place for migratory birds, and create a rich outdoor classroom.

What is there to do at Indiana Dunes? Lots.

You can explore the lakeshore's environment by examining glacial moraines left behind 14,000 years ago by retreating Wisconsin glaciers, fishing the Little Calumet River, or strolling through an oak forest. Tours of Pinhook Bog are possible, too, though you must go with a ranger.

Kayakers can paddle along a 15-mile (24-kilometer) stretch of the Lake Michigan Water Trail that runs between Chicago, Illinois, and Michigan City, Indiana. When completed, the water trail is expected to loop along the entire 1,600-mile (2,575-kilometer) coastline of Lake Michigan.

Portage Lakefront and Riverwalk within the park is operated by the City of Portage under an agreement with the National Park Service. One of the most popular beach areas along the entire national park, it provides easy access to the lakefront, multi-use trails, an accessible fishing pier and a restored 900-foot (274.3-meter) breakwater. A 3,500-square-foot (325.2-square-meter) public pavilion includes restrooms, a seasonal snack bar and a glass walled classroom and meeting space.

You can explore Eastern Great Marsh, a historic and extensive wetland. it is located in a dune-beach complex less than one mile from Lake Michigan and is situated between two large dune systems. The eastern section of Great Marsh is approximately 500 acres (202.3 hectares). Historically, Eastern Great Marsh was comprised of a variety of wetland types including a tamarack swamp, sedge meadow, wet-mesic prairie, shallow and deep marsh, and a shallow lake called Fish Lake. Human activities at the site over the last century have resulted in significant alteration to hydrology, plant assemblages, and ecosystem services.

The park hosts several festivals:

• Maple Sugar Time Festival held the end of February or first weekend of March where you can learn about and take part in the sugaring operation at historic Chellberg Farm.
  
  
• Indiana Dunes Birding Festival held in mid-May where you can attend dozens of guided field trips and car pool tours to view migrating birds within the dunes area, enjoy more than 50 bird-related programs ranging from live bird of prey talks to species ID workshops, and sign up for special workshops for both new bird watchers and educators.
  
  
• Indiana Dunes Outdoor Adventure Festival in early September to celebrate and engage in outdoor activities offered in the park, from hiking to biking to photography to yoga and more.

Winters are too cold for swimming in Lake Michigan, but there are all sorts of winter activities including hiking, snowshoeing, and cross-country skiing at places like the Glenwood Dunes Trail. This 6.4-mile (10.3-kilometer) trail is a series of interconnecting loops that meander through gently rolling wooded dunes.

Come fall, attend the annual tour of four historic homes from the 1933 Chicago World’s Fair. This one-day event is held on the last weekend of September. These limited tours are available by reservation only. Each tour lasts two hours and includes an inside look at the Cypress Log Cabin, Florida Tropical, Armco Ferro, and the Wieboldt-Rostone houses.

Of course, you can also simply head to the beach, spread out your blanket, prop yourself up in a beach chair, and enjoy a good book or the mesmerizing waves coming ashore.
