Indiana Dunes · Mile 01 · The Story

Fifteen miles of dunes,
between two steel towns.

Indiana Dunes protects fifteen miles of Lake Michigan shoreline squeezed between the industrial cities of Gary and Michigan City, an unlikely setting for a national park that also happens to rank among the most biologically diverse in the entire system. Wind and waves have shaped this shoreline for millennia, creating a compressed sequence of habitats, from open beach to dune to woodland to wetland, that can shift dramatically within a few hundred feet of walking.

Mount Baldy, a 126-foot dune on the park's eastern end, is slowly moving inland and burying the forest behind it, a process visible enough that visitors are no longer allowed to climb the dune itself due to a partially collapsed sand pocket. The park was upgraded from a national lakeshore to a full national park only in 2019, a designation change that surprised even some longtime Indiana residents who hadn't fully registered a national park existed in their own backyard.

Come for the dunes and the lake. Stay for the fact that a genuinely wild ecosystem survives this close to major industry. Read the story, trust the live data above for what is open today, and when you leave, mark it visited.

The park became a full national park only in 2019, upgraded from a national lakeshore designation held since 1966.

Fact 04

Research on plant succession conducted here by ecologist Henry Cowles in the early 1900s helped found the field of plant ecology as a scientific discipline.

Indiana Dunes National Park FAQ

The questions people actually ask, answered from the park’s own current guidance. Fees and permit rules change every year, so each answer links back to the National Park Service page it came from.

No, Indiana Dunes National Park has no entrance fee, unlike most national parks. You will pay separately for things like camping at Dunewood Campground or reserving a picnic shelter at West Beach or Bailly/Chellberg through recreation.gov. Source: NPS.gov

Most of the park's public areas are open daily from 6 a.m. to 11 p.m., though Kemil Beach stays open 24 hours and Porter Beach and West Beach close earlier at 9 p.m. Dunewood Campground is seasonal, running from April 1 through November 1, but the beaches and trails themselves are accessible year-round including in winter. Source: NPS.gov

Swimming comes with real risk here because rip currents are, in the park's own words, the most significant drowning threat on Lake Michigan. If you get caught in one, swim parallel to shore rather than fighting it until the pull lets up. Lifeguards are only on duty at West Beach, from the Friday of Memorial Day weekend through Labor Day, 10 a.m. to 6 p.m., and the park also monitors beaches for bacteria, closing the water to swimming when levels are posted as unsafe.
