Sand dunes, wild orchids, and Chicago skyline views: Indiana’s secret national park delivers

It’s a national park most Americans have never heard of

Fifty miles southeast of Chicago, Indiana has a national park that most people outside the Midwest have never put on their radar.

It runs 15 miles along the southern shore of Lake Michigan, covers more than 15,000 acres, and ranks fourth among all national parks for plant diversity. That puts it ahead of places far more famous.

You get sand dunes, ancient wetlands, wild orchids, and a clear-day view of the Chicago skyline from the beach. The deeper you look, the stranger and better it gets.

How a botanist and a schoolteacher saved these dunes

The dunes along Lake Michigan’s southern shore drew serious scientific attention back in the 1890s, when University of Chicago botanist Henry Chandler Cowles came here to study how plants take root and spread across bare sand.

His research helped establish ecology as a formal science, and the area became known as the birthplace of American ecology. But the land itself nearly disappeared to industry.

In 1952, a local teacher named Dorothy Buell gathered a group of women at her kitchen table and founded the Save the Dunes Council.

Illinois Senator Paul H. Douglas carried the fight to Congress, and the Indiana Dunes National Lakeshore became official in 1966.

Clear days give you the Chicago skyline from the beach

The park has several beaches spread across its 15-mile stretch of Lake Michigan shoreline, and each one has its own feel.

West Beach draws the biggest crowds and comes with seasonal lifeguards, restrooms, and picnic areas. Kemil Beach and Dunbar Beach run quieter, with fewer people and open views across the water.

On a clear day, you can see the Chicago skyline from the sand, which is a strange and satisfying thing to look at while standing in Indiana.

Lake Michigan moves like an ocean, with real currents and conditions that can shift fast, so pay attention.

The 3 Dune Challenge will absolutely work your legs

Indiana Dunes State Park sits inside the national park’s boundaries but runs separately, with its own entrance fee.

That’s where you’ll find the 3 Dune Challenge, a 1.5-mile trail that takes you up three of the tallest dunes on the lake’s southern shore. Mt. Jackson stands 176 feet.

Mt. Holden reaches 184 feet. Mt. Tom tops out at 192 feet.

Together, they pack 552 vertical feet of climbing, with slopes as steep as 40 degrees. Sand is about 1.6 times harder to walk on than solid ground, and you’ll feel it.

Finish all three and you can pick up a free commemorative sticker at the visitor center.

Walk through a grove of jack pines growing straight out of the sand

The Dunes Succession Trail at West Beach is about a mile long, but the sandy footing makes it feel longer.

The trail takes you through four stages of dune-to-forest change, from open sand all the way to mature woodland, including a grove of jack pine trees growing right out of the dune.

A climb up roughly 270 stairs opens up views of Lake Michigan and the Chicago skyline.

The trail carries another name, too: the Diana of the Dunes Dare, a nod to Alice Mabel Gray, a woman who left Chicago in the early 1900s to live alone among these dunes.

In May, millions of lupine flowers bloom across a rare oak savanna

The Paul H. Douglas Trail through Miller Woods runs 3.4 miles through wetlands, open dunes, and one of the last surviving black oak savannas in the world.

Named for the senator who fought to protect this land, the trail was also chosen as the site where Indiana Dunes National Park was officially dedicated in 2019.

Come in May and the savanna floor turns purple with millions of blooming lupine flowers. Outside of that window, the black oaks and open grassland still hold their own.

This is not a habitat you can find just anywhere.

Mount Baldy moves four feet every year and you can’t climb it alone

Near the eastern end of the park, Mount Baldy rises 126 feet above Lake Michigan.

Unlike the other dunes, it has no vegetation to hold it in place, so wind and weather push it about four feet inland every year.

That’s what makes it a living dune, and that’s also why the summit is closed to free-climbing. You can only reach the top on a ranger-led hike, offered on select weekends.

The beach below stays open year-round, and the dune above you shifts a little more each season, whether you watch it or not.

Spot sandhill cranes in a wetland that’s 4,000 years old

Cowles Bog is named for the botanist who did his landmark research here, and at 4,000 years old, it’s one of the most ecologically significant wetlands in the region.

Despite the name, it’s technically a fen, fed by groundwater rather than rain alone.

It was named a National Natural Landmark in 1965 and sits on the National Audubon Society’s list of Important Bird Areas.

The Great Marsh Trail runs a flat 1.2 miles through the largest interdunal wetland in the Lake Michigan watershed.

From the accessible observation deck, you can watch sandhill cranes, herons, wood ducks, and warblers move through.

Three carnivorous plants live in this bog, and it floats on a hidden lake

Pinhook Bog is one of only two true bogs in Indiana, and what’s underneath it is the reason it works the way it does.

A floating mat of sphagnum moss sits on top of an ancient, hidden lake, creating conditions where pitcher plants, sundew, and bladderwort all survive by catching and digesting insects. Native orchids grow here too.

The ecosystem is fragile enough that the park only opens the bog during ranger-led tours on limited dates in summer and early fall.

It sits about a 20-minute drive east of Chesterton, and there’s nothing else quite like it.

Five homes from a 1933 World’s Fair crossed Lake Michigan by barge

Along the lakefront in Beverly Shores, five houses from the 1933 Chicago World’s Fair still stand inside the national park.

A developer named Robert Bartlett bought them after the fair closed and moved them across Lake Michigan by barge, hoping to sell real estate in his resort community.

They include the Florida Tropical, the Cypress Log Cabin, and the House of Tomorrow, designed with floor-to-ceiling glass walls and the first residential dishwasher ever installed.

Four have been restored through a partnership with Indiana Landmarks. Tours run only one day a year, usually in October, and they sell out fast.

A fur trader’s homestead and a Swedish family’s farm are both still standing

Two historic sites near the western end of the park take you back to northwest Indiana’s earliest settlers.

French-Canadian fur trader Joseph Bailly built his homestead here around 1822, making him one of the first non-native settlers in the region.

The main house, now a National Historic Landmark, has been restored to its 1917 appearance. Just down the road, Chellberg Farm tells a different story.

Swedish immigrants Anders and Johanna Kjellberg bought the land in 1869, and three generations of their family worked it before selling to the National Park Service in 1972.

The farm still runs with livestock, a 1870s barn, and a maple sugar shack used every spring.

Over 350 bird species pass through here, and a festival celebrates every May

Indiana Dunes ranks as the top birding destination in the state, with more than 350 bird species recorded across the park.

Cowles Bog, the Great Marsh, West Beach, and Miller Woods each draw different species at different times of year.

You can spot red-headed woodpeckers, great blue herons, dozens of warbler species, and sandhill cranes, depending on the season.

Every May, the Indiana Dunes Birding Festival brings guided field trips, workshops, and live bird programs to the park.

Free self-guided birding tour maps are available at the Indiana Dunes Visitor Center if you’d rather go at your own pace.

Visit Indiana Dunes National Park in Indiana

You can reach Indiana Dunes National Park by car from Interstate 94 or on the South Shore commuter train from Chicago, which makes four stops inside the park.

The best place to start is the Indiana Dunes Visitor Center at 1215 North State Road 49 in Porter, where rangers can help you plan your day and point you toward maps and exhibits.

The national park entrance fee is $25 per vehicle for a seven-day pass, and the America the Beautiful pass is accepted. Indiana Dunes State Park, which sits inside the national park, charges a separate fee.
