10 Best Things to Do in Indiana Dunes National Park

Most people who've heard of Indiana Dunes think of it as a beach with a fancy label, and I get why — it's genuinely one of the most convenient beach days you can have from Chicago. But the park is also fourth among all national parks in biological diversity for its size, sitting at a strange ecological crossroads that packs an outsized variety of plant and animal life into a narrow shoreline strip. Here's my honest list of what's actually worth your time.

Best Time of Year to Visit, and Why

For the beach, I'd go June through August — that's when West Beach has lifeguards on duty (Memorial Day weekend through Labor Day, roughly 10am to 6pm) and the water's actually warm enough to want to be in it. But I wouldn't write off the shoulder seasons. Spring and fall are when the birding gets genuinely excellent — the park sits right at the southern tip of Lake Michigan, which funnels migrating birds along the shoreline, and it's recorded over 350 bird species, among the highest counts of any national park. Fall also brings cooler temperatures that make the longer dune hikes, like Cowles Bog, much more comfortable than they are in July humidity.

How Indiana Dunes Compares to Cuyahoga Valley

These two come up together a lot since they're both "surprise" national parks sitting close to a major metro instead of out in the wilderness. Here's my honest comparison:

	Indiana Dunes	Cuyahoga Valley
Terrain	Lake Michigan shoreline, sand dunes, beach and wetland	Wooded river valley, waterfalls, sandstone ledges
Signature feature	The dunes themselves, plus West Beach	Brandywine Falls
Nearest metro	Chicago, IL — about an hour	Cleveland / Akron, OH — both under 45 min
Best for	A summer beach day near the city	A fall-color hiking day, or a shoulder-season weekend
Entrance fee	Paid entrance (day-use fee applies once you stop to use a trail or beach)	Free, no gate, open year-round

If I had to pick one, I'd pick based on the season, same as I'd tell a Cuyahoga Valley visitor: Indiana Dunes in July for the beach, Cuyahoga Valley in October for the color. They're different enough experiences that this isn't really a rivalry so much as a calendar decision.

Beach-Day Checklist — Indiana Dunes National Park

This is a beach park more than a backcountry one, so the gear list looks different from a mountain park's:

1. Swimsuit and a real beach towel — West Beach is the only lifeguarded option, but several of the park's other beaches are open too and less crowded.
2. Reef-safe sunscreen, reapplied — there's zero shade on open sand and dune tops, and I underestimated how much sun exposure a few hours on the beach adds up to.
3. Water shoes or sandals with a real sole — dune sand gets surprisingly hot by midday, and some of the interior trails cross rougher, root-covered ground.
4. A large refillable water bottle — same logic as the sunscreen; there's no shade to hide in in between water breaks on the dune trails.
5. A bike if you want to ride the Oak Savannah Trail — it's a flat, paved, easy 4-mile route, a nice change of pace from beach walking.
6. A dry bag or plastic bag for wet clothes — if you're doing beach and trails in the same day, you'll want somewhere to stash a wet swimsuit before you get back in the car.

The 10 Best Things to Do in Indiana Dunes National Park

1. 1. West Beach

   The park's only lifeguarded beach, with a bathhouse, showers, and a view across the lake to the Chicago skyline on a clear day. Lifeguards on duty Memorial Day weekend through Labor Day. Easy, 2–4 hrs.

2. 2. Mount Baldy Beach Trail

   The park's tallest active dune, slowly burying the forest behind it. The summit and dune face are closed to general access due to sand-collapse risk — ranger-led hikes are the only way to the top — but the beach-level trail around the base is open and worth doing on its own. 0.75 mi, moderate to rugged, ~1 hr.

3. 3. Cowles Bog Trail

   The birthplace of modern plant ecology — Henry Chandler Cowles studied plant succession here in the 1890s, and you can walk the same transition from beach to dune grass to wetland to forest on this loop. 4.7 mi loop, moderate to rugged, ~4 hrs.

4. 4. Paul H. Douglas Trail (Miller Woods)

   A trail through the Miller Woods interdunal wetlands, named for the U.S. senator who championed the park's creation. A good look at the marshy, less-photographed side of the dune ecosystem. 3.4 mi, moderate, ~2 hrs.

5. 5. Glenwood Dunes Trails

   A network of interior trails through older, wooded dune ridges further from the lake — quieter than the beachfront trails and a good half-day hike if you want real distance. 6.8 mi, moderate, ~4 hrs.

6. 6. Bailly Homestead, Chellberg Farm & Little Calumet River Trails

   A preserved 1820s trading-post homestead and a working 19th-century farm connected by an easy river trail — the park's best look at the human history of the area before it became parkland. 3.4 mi, easy to moderate, ~2.5 hrs.

7. 7. Heron Rookery Trail

   A quiet, easy trail along the Little Calumet River in a separate, inland section of the park — a nice detour if you want a break from sand and crowds. 3.3 mi, easy, ~2 hrs.

8. 8. Portage Lakefront and Riverwalk Trail

   A short, easy walk near the Portage Marina and Lakefront Pavilion, with a nice mix of lakefront and river views. Good for a quick stop if you're passing through the western end of the park. 0.9 mi, easy, ~45 min.

9. 9. Great Marsh Trail

   An easy, flat walk through the largest interdunal wetland in the park — genuinely good for birding, especially in spring and fall migration. 1.3 mi, easy, ~1 hr.

10. 10. Oak Savannah Bike Trail

    A flat, paved bike route connecting to the regional trail network — the easiest way to cover ground here without a car, and a nice change of pace from sand underfoot. 4 mi one-way, easy, ~2 hrs.
