The park contains the '3 Dune Challenge,' a 1.5-mile hike that requires summiting the three highest dunes in the park.
It is a globally significant location for bird migration, with over 350 species recorded in the area.
The dunes themselves are constantly shifting due to wind and wave action, representing a dynamic ecological environment.
The park was established in 1925 after a decade-long conservation campaign to prevent industrial development along the shoreline.
The sand in the dunes is composed primarily of quartz, deposited by glaciers during the last ice age.
The park features a unique 'dune succession' ecosystem, a phenomenon first studied by botanist Henry Chandler Cowles in the late 1890s.
Indiana Dunes State Park spans over 2,000 acres along the southern shore of Lake Michigan in Chesterton, Indiana. The park features three major sand dunes, Mount Tom, Mount Holden, and Mount Jackson, which rise nearly 200 feet above the lake level. Visitors have access to three miles of beach frontage characterized by fine sand and expansive views of the Chicago skyline on clear days. The terrain includes a mix of rugged dune formations, forested wetlands, and coastal marshes. Over 70 miles of hiking trails navigate through these diverse ecosystems within the adjacent Indiana Dunes National Park and the state park boundaries. The site is a primary location for observing migratory bird species throughout the year. Facilities include a historic pavilion, picnic shelters, and established campgrounds. The park's geomorphology is shaped by glacial activity that formed the Lake Michigan basin.

Bring a sturdy pair of hiking boots for the steep, shifting sand trails.
Visit on a weekday if possible to avoid heavy weekend crowds at the beach.
Check the Indiana Department of Natural Resources website for trail closures due to high water levels or erosion.
Attempting to climb dune faces outside of marked trails, which damages the ecosystem and risks injury.
The park is open year-round, though specific trail conditions may vary due to winter ice or seasonal maintenance.
Stay on marked trails to prevent erosion and protect sensitive dune vegetation; pack out all trash.
