Indiana has a dune that swallows parking lots and it’s an hour from Chicago

It’s an hour from Chicago

Fifteen miles of Lake Michigan beach sit in northwest Indiana, and most people drive right past them.

Indiana Dunes National Park covers about 15,000 acres along the southern shore, and it became the nation’s 61st national park on Feb. 15, 2019, after spending more than 50 years as a national lakeshore.

The effort to protect this land goes back to 1899. Nearly 3 million people visit every year, and what they find here goes well beyond sand.

A glacier left behind seven shorelines

Everything you see at Indiana Dunes started more than 14,000 years ago, when the last continental glacier pulled back and carved out the Great Lakes.

As Lake Michigan’s water levels shifted over thousands of years, they left behind as many as seven different shorelines. Wind piled the sand into layers of dunes, and wetlands filled the valleys between them.

Plants slowly moved in, starting with grasses, then shrubs, then full forests.

In the 1890s, University of Chicago botanist Henry Cowles studied that process right here and helped launch the modern science of ecology.

Arctic plants grow next to cactus

For a park that covers just 15,000 acres, the variety of life here is hard to believe. More than 1,100 native plant species grow in the park, from Arctic bearberry to prickly pear cactus.

Over 350 bird species pass through, along with 46 mammal species, 23 reptile species, 18 amphibian species, and 71 fish species. The black oak savannas here rank among the last surviving oak savannas on the planet.

Size has nothing to do with it.

You can see the Chicago skyline from the sand

The park’s 15 miles of beach stretch along Lake Michigan and feel almost oceanic on a big-wave day. West Beach draws the most people, with restrooms, picnic shelters, and trails nearby.

If you want space, head to Kemil Beach or Dunbar Beach, where the crowds thin out and the views open wide.

Portage Lakefront sits on land that was once a steel mill toxic waste dump, now fully reclaimed with a beach and pavilion. On clear days, you can spot the Chicago skyline across the water.

Climb 552 vertical feet in 1.5 miles

The 3 Dune Challenge takes you up the three tallest dunes in Indiana Dunes State Park, which sits inside the national park’s borders.

You summit Mount Jackson at 176 feet, Mount Holden at 184 feet, and Mount Tom at 192 feet, covering 552 vertical feet in just 1.5 miles. The trail is steep and sandy, so it hits harder than the distance suggests.

Finish the whole thing and you can grab a sticker at the Nature Center as proof.

Mount Baldy swallows everything in its path

Mount Baldy stands 126 feet tall and moves inland about four feet every year.

Wind and erosion reshape it constantly, and over time it has buried trees, picnic areas, and parts of its own parking lot.

In spring 2026, crews temporarily closed the access site to relocate about 40,000 cubic yards of sand that had swallowed the parking area.

That sand is heading to Crescent Beach as part of a shoreline project with the U.S. Army Corps of Engineers. You can reach the summit only on ranger-led hikes offered summer weekends.

Fifty miles of trails through prairies and bogs

More than 50 miles of hiking trails and 37 miles of biking trails spread across 15 trail systems in the park.

The Paul H. Douglas Trail on the western edge winds through restored prairies and Miller Woods, and it feels worlds away from the development nearby.

Cowles Bog Trail cuts through a National Natural Landmark where carnivorous pitcher plants grow.

The Great Marsh Trail is flat and easy, ending at a deck above the largest wetland complex in the Lake Michigan watershed. Heron Rookery Trail follows the Little Calumet River and fills with wildflowers in spring.

Glider flights here inspired the Wright brothers

In the summer of 1896, French-born engineer Octave Chanute brought experimental gliders to the Indiana Dunes to test them.

The dunes gave him everything he needed: steady winds, launch-ready hills, and soft sand for landings. Chanute and his team completed several hundred successful flights that summer.

His published results and biplane glider design went on to directly inspire Wilbur and Orville Wright as they worked toward powered flight.

You can learn about those experiments at the Aquatorium at Marquette Park, a National Historic Landmark.

Five World’s Fair homes crossed Lake Michigan by barge

Along Lake Front Drive in Beverly Shores, five homes from the 1933 Chicago World’s Fair still stand inside the national park. They were part of the Homes of Tomorrow exhibit, which drew nearly 50 million fairgoers.

After the fair closed, developer Robert Bartlett bought the homes and moved them by barge across Lake Michigan to his resort community.

All five sit on the National Register of Historic Places, and four have been restored through a partnership between Indiana Landmarks and the National Park Service. The Cypress Log Cabin is now available for overnight stays.

Interior tours happen one day a year in October and sell out fast, but you can view the homes from the road anytime.

Walk on a floating bog with a ranger

Pinhook Bog is a quaking bog that formed thousands of years ago, and the National Park Service designated it a National Natural Landmark in 1965. The ground moves under your feet.

Sphagnum moss, leatherleaf, and insect-eating pitcher plants grow here, species you rarely see this far south. You can only explore it on ranger-led hikes offered summer weekends.

Beyond the bog, the park holds restored prairies, forested wetlands, and remnants of tallgrass prairie on ancient shoreline ridges. All of it packed into one small park.

350 bird species fly through every year

The park sits right at the southern tip of Lake Michigan, directly in the path of major migration routes. Spring and fall send waves of raptors, songbirds, waterfowl, and wading birds through the area.

The Great Marsh observation deck is where you want to be for herons, sandhill cranes, egrets, and warblers. The Longshore Birding Platform and Portage Lakefront also draw birders looking for good sight lines.

Every May, the Indiana Dunes Birding Festival brings guided walks and expert-led programs to the park.

Ice shelves form on the lake in winter

Summer is peak season, with swimming, lifeguards at select beaches, and a full schedule of ranger-led programs.

Fall brings smaller crowds, changing leaves, and the annual Century of Progress home tour in October, which sells out fast. Winter turns the park into something else entirely.

Ice shelves build up along Lake Michigan, the beaches go empty, and you can cross-country ski or snowshoe through the dunes. Spring fills the river trails with wildflowers and returning birds.

The park stays open year-round, and the visitor center is staffed 362 days a year.

Visit Indiana Dunes National Park in Indiana

You can reach Indiana Dunes National Park in about an hour from Chicago.

The park runs along the southern shore of Lake Michigan in northwest Indiana, and it stays open daily from 6 a.m. to 11 p.m. Stop at the Indiana Dunes Visitor Center at 1100 North Mineral Springs Road in Porter, Ind. A seven-day vehicle pass runs $15 to $25.

Check the official website for ranger-led hike schedules, especially for Mount Baldy and Pinhook Bog, since those fill up.
