A new federal recreation report puts some hard numbers on something Hoosiers have been saying for years. Indiana Dunes National Park is not a minor stop on the national park map. It is one of the busiest units the National Park Service runs.
The park logged 2,629,497 recreation visits in 2025. For scale, in that same year Bryce Canyon drew 1.97 million, Mount Rainier 1.64 million, Arches 1.51 million, and Everglades 778,000. The Dunes beat all of them, from a shoreline you can reach from Indianapolis in under three hours.
Where the Dunes Rank
The federal report covered by WKVI ranked Indiana Dunes 36th out of 398 National Park Service units, which lands it in the top ten percent. Widen the lens to all 1,824 federal recreation sites and it comes in 70th, inside the top five percent.
Those activity figures come from the FY2024 Interagency Recreation Visitation Data Report, produced by the Federal Interagency Council on Outdoor Recreation. That report exists because of the EXPLORE Act, the outdoor recreation law enacted in January 2025, which directed the agencies to actually count this stuff in a consistent way. Sightseeing accounted for about 2.34 million visits and hiking for about 1.27 million.
One caveat worth stating plainly, since these numbers get mashed together constantly. The 2,629,497 figure is calendar year 2025. The activity breakdown is fiscal year 2024. They are different windows, so do not add them up.
What You Are Actually Getting
Indiana Dunes National Park covers roughly 16,000 acres, with 15 miles of Lake Michigan shoreline and about 50 miles of trails across 14 trail systems. The reason it draws numbers like this is not the beach alone. The park sits on one of the most biodiverse patches of land in the entire park system, with more than 1,100 species of ferns and flowering plants. Among them are 28 native orchids, which is more native orchid species than the entire state of Hawaii. The Park Service ranks the Dunes fourth among all national parks for biological diversity, which is absurd for a park this size sitting next to steel mills.
Those steel mills are part of the experience, not a footnote. This is the rare park where you can stand on an ancient dune, look past rare wildflowers, and see working blast furnaces on one side and the Chicago skyline floating on the horizon across the water on the other. Some visitors find it jarring. It is also the honest picture of what this shoreline is: a strip of wilderness that survived heavy industry closing in from both sides, which is most of the reason it took decades of fighting to protect.
The Two-Park Thing That Trips Everybody Up
Here is the part that confuses even people who go every summer. There are two parks, and they are not the same place.
Indiana Dunes National Park is federal, roughly 16,000 acres, headquartered in Porter. It was authorized in 1966 as Indiana Dunes National Lakeshore and redesignated as the country's 61st national park on February 15, 2019.
Indiana Dunes State Park is run by Indiana DNR, covers 2,182 acres, dates to 1925, and sits in Chesterton inside the national park's boundary.
This matters most when you go to book a campsite. The state park has 140 electric sites and is open year-round. The national park's Dunewood Campground has 67 sites, no electric or water hookups at all, and closes from November 1 to April 1.
Do not read "no hookups" as primitive, though. Dunewood is split into two loops, Douglas and Mather, and each one has restrooms and showers in the middle of it, with potable water at several spots and an RV dump station on site. What you cannot get is a hookup at your own site. If you want a 50-amp connection in December, the state park is your only option, and the Park Service says so on its own site.
