Where the Sand Dunes Meet the Shores of Lake Michigan

The Dune Succession Trail at Indiana Dunes National Park is one of the most quietly remarkable short hikes in the National Park System — not because of what happened here, but because of what is still happening. This one-mile loop at West Beach walks you through four distinct stages of ecological succession, from open sand on the Lake Michigan shoreline through a sheltered jack pine grove, up 250 to 270 boardwalk stairs to a sweeping dune-crest view over the water, and back down to the beach. It is a trail where the geology, the botany, and the view all work together to tell the same story: how this shoreline has been building itself, one generation of plants at a time, since the glaciers retreated roughly 14,000 years ago.

Indiana Dunes National Park is one of the most visited national parks in the country and one of the most ecologically diverse — home to over 350 bird species and nearly 1,100 plant species within a surprisingly compact stretch of Lake Michigan shoreline. The Dune Succession Trail is the park’s signature short hike and its best single introduction to what makes Indiana Dunes unlike anywhere else.

Getting to the Trailhead

The Dune Succession Trail begins at the West Beach area of Indiana Dunes National Park, accessed via West Beach Road off County Line Road near Gary, Indiana. The large West Beach parking lot has room for several hundred cars. The trailhead is at the northeast corner of the parking lot, where the trail joins the road heading toward the bathhouse. Follow the road toward the lake — the trail breaks off to the left about 0.2 miles before you reach the bathhouse, marked by signage pointing into the dunes. The road itself becomes the return leg of the loop, making this a true point-to-point circuit back to the parking area.

Indiana Dunes National Park sits on the southern shore of Lake Michigan in northwest Indiana, roughly 40 miles southeast of downtown Chicago. It is easily reached from Chicago via I-90/94 or the South Shore Line commuter rail — making it one of the most accessible national parks in the country for urban visitors. From Indianapolis, the drive is about two hours north on I-65.

Hiking the Trail

From the trailhead at the northeast corner of the parking lot, the trail immediately steps onto boardwalk and begins climbing into the dunes. The boardwalk is the defining feature of the first section — it guides you up and over the initial dune face while protecting the fragile vegetation on either side. Marram grass and cottonwood anchor the sand here, pioneer species doing the slow work of stabilizing a surface that would otherwise shift with every wind. This is Stage One of the succession the trail is named for, and the boardwalk puts you right in the middle of it.

The trail descends into the swale between the first and second dune ridges, where the jack pine grove waits — and the character of the hike changes entirely. The jack pines are low and wind-sculpted, clinging to a sandy substrate that most trees cannot tolerate. They are Stage Two: pioneer trees that moved into open dune sand long after the grasses arrived, providing shade and organic matter that will eventually allow the black oaks and hickories of the mature forest to take hold. Standing in the grove, sheltered from the lake wind, it is easy to forget you are on a dune at all. Take your time here. It is one of the quietest and most distinctive spots on any trail in the Great Lakes region.

From the swale, the trail climbs again — and this is where the stairs begin. The boardwalk ascends the face of the second dune ridge in a long, sustained staircase of 250 to 270 steps. It is a genuine workout, but the view building with every landing keeps you moving. At the crest, the lake opens up: Lake Michigan, wide and blue-grey, stretching north to the horizon. On a clear day, the Chicago skyline appears to the west across the water. Even in overcast conditions, the scale of the view is arresting — an inland sea, framed by dune grass and the tops of oaks below.

Highlights Along the Way

The Boardwalk and the Four Stages of Succession

The trail’s name is its curriculum. Ecological succession is the process by which bare ground is progressively colonized by increasingly complex communities of plants and animals over time — and the Indiana dunes are one of the places where that process was first formally studied. In the early 1900s, University of Chicago botanist Henry Cowles conducted groundbreaking research here, documenting how plants colonize open sand and gradually transform it into forest. The concept he developed — plant succession — became foundational to the science of ecology. Walking the Dune Succession Trail, you are walking through Cowles’s original field site, with the four stages of that progression laid out before you in the space of a single mile: open sand, cottonwood and marram grass, jack pine, and mature deciduous forest.

The Jack Pine Grove

The grove in the swale between the first and second dune ridges is one of the most memorable spots on the trail. Jack pines are tough, resinous trees adapted to poor soils and fire — in many ecosystems they depend on fire to open their cones and release seeds. Here, they fill a transitional role: too hardy for bare sand, too shade-intolerant to survive once the oaks close in above them, they occupy an ecological middle ground that exists only because the dunes keep shifting the timeline. Every swale and ridge at West Beach is at a slightly different stage of succession, which is why the grove feels like its own enclosed world rather than simply a section of larger forest.

The Dune Crest and Lake Michigan View

The climb up the boardwalk stairs delivers one of the better views available on a short trail anywhere in the Midwest. From the dune crest, Lake Michigan dominates the northern horizon — one of the five Great Lakes, holding roughly 21 percent of the world’s surface fresh water. The Chicago skyline, visible on clear days about 40 miles to the west, provides a striking contrast: one of the world’s great cities, framed by a glacially formed freshwater sea and a shoreline that has been ecologically active for ten thousand years. The descent from the crest drops you quickly through mature deciduous forest — black oak, sassafras, hickory — before the trail emerges onto the beach.

West Beach and the Return Loop

The trail deposits you onto West Beach, where the sand is wide and the lake stretches away to the north. A short walk along the shoreline before climbing the steps back up to the bathhouse reminds you how unusual this landscape is — a Great Lakes beach within an hour of one of the largest cities in North America, protected as a national park since 1966 and elevated to full National Park status in 2019. The return leg follows West Beach Road back through the parking area, completing the loop through all four ecological zones in the space of about a mile.

What Makes This Trail Special

The Dune Succession Trail is short, but it earns its place in the National Park System. In about a mile, it walks you through a living ecology textbook — the same landscape where the science of plant succession was born — while delivering a lake view that stops most people in their tracks. The jack pine grove in the swale is something you don’t expect and don’t forget. The stairs are a genuine workout that pays off at the top. And arriving on the beach at the end, stepping out of the forest onto Lake Michigan sand, is one of those small trail moments that lands differently than it has any right to. Indiana Dunes is one of the most ecologically complex and historically significant stretches of shoreline in the country, and the Dune Succession Trail is the best single hour you can spend understanding why.

Tips for Visiting

The Science of the Dunes — and the Park’s History

Indiana Dunes National Park exists in part because of its science. In the early twentieth century, University of Chicago botanist Henry Cowles studied the succession of plant communities on these dunes and published findings that helped establish ecology as a formal discipline. His work showed that bare sand dunes were not static landscapes but dynamic systems moving through predictable stages of plant colonization — a concept that reshaped how scientists understood the natural world. The dunes Cowles studied are the same dunes you walk through on the Succession Trail today.

The park itself has a longer history of advocacy. Environmental champion Stephen Mather, the first director of the National Park Service, championed the preservation of these dunes in the 1910s. Decades of local advocacy — led in part by poet Carl Sandburg and conservationist Jens Jensen — eventually resulted in the creation of Indiana Dunes National Lakeshore in 1966. In February 2019, Congress redesignated it as Indiana Dunes National Park, making it one of the newest units in the National Park System and one of the most visited.

Final Thoughts

The Dune Succession Trail does not ask a lot — a mile, an hour, a good pair of shoes for the stairs. What it offers in return is harder to summarize: a forest growing out of sand, a grove of jack pines that feels like its own world, a lake view earned step by step, and a beach at the end that makes the whole loop feel like a small and complete story. Indiana Dunes National Park is closer to more Americans than almost any other unit in the system, and the Dune Succession Trail is the best single argument for why it deserves the trip.
