Indiana Dunes National Park is mostly visited for the dunes, but there’s another side to the park that doesn’t get as much attention: the wetlands. I think hiking the Great Marsh Trail is one of the best ways to explore it. This easy, 1.3-mile loop winds through the largest interdunal wetlands along Lake Michigan. It’s also perfect for birdwatching, checking out wildlife and enjoying the peaceful marshy area with family and dogs. If you’re planning a trip to Indiana Dunes, staying nearby makes early hikes easy. We stayed in Chesterton, just a short drive away. You can find local hotels here. We hiked this trail in early May, just before noon, and found this to be a perfect time to visit. We had cool spring weather, a bright blue sky and the sun overhead prevented us from feeling cold (perfect weather for pants and a sweater!). The trail itself is mostly shaded and quiet. Even though it’s just over a mile, we spent a full hour wandering slowly, stopping at the observation deck to watch birds, take photos of mushrooms growing in the trees and just enjoy time by the marsh. Why Hike the Great Marsh Trail My parents joined us from Wisconsin while we were on a road trip to Ohio for the Sonic Temple Festival, and we wanted a short, easy hike that everyone (including our dogs, Toby and Lily) could enjoy. We wanted to explore the marsh but also do some birdwatching. Minerva is getting into birdwatching, and my mom uses an app to identify birds around us. This trail also came highly recommended by park rangers because of that, too. This way to the observation deck! Yellow flowers along the trail The trail is flat, shaded and easy. But ticks were out in full force in May. Both of our dogs picked up about 10 each, so we’d recommend bringing tick repellant and double-checking yourself (and your pups) before getting back in the car (and again when you get home). Even with the tick “attack”, the trail is worth it. With only a couple of other hikers around, it felt like we had the marsh to ourselves. The birds calling back and forth across the wetland and reeds swaying in the breeze made it easy to slow down and enjoy the Great Marsh hiking trail. Trail Overview: Map, Parking & What to Expect Finding parking for the trail is easy. There are two lots north of U.S. Highway 12 on Broadway Avenue. We parked at the South main gravel lot, but there’s a smaller North lot with a handicap space if you need them. You can see the small South parking lot in the distance If you’re flying into Chicago or South Bend, definitely grab a rental car, it makes getting around the park so much easier. You can compare prices here to see what fits your trip best. The Great Marsh Trail is a flat, easy, short and sweet 1.3-mile trail. We took our time and it still only took about an hour. You’ll mostly be walking on dirt and grass, with some gravel in places. It can get a little muddy and slippery near the edges of the marsh, so be careful not to fall in! What we loved was that this is a dog-friendly trail! Just make sure your furry friend is on a six-foot leash. Both Toby and Lily loved sniffing around, but, again, be careful of ticks!

Or View on AllTrails About halfway through the loop, there’s an observation deck with a couple benches where we sat for a while to rest, listen to the birds and enjoy the views of the marsh. You’ll find benches along the observation deck The marsh itself is the real highlight of this trail. Over the past 20+ years, this area has been restored after decades of drainage and degradation. Ditches have been filled, culverts have been plugged and native grasses and wildflowers have been reintroduced. Every muddy patch you see is a sign the marsh is coming back, water is returning and wildlife is thriving. 🔬 Science with Sam: The Great Marsh is a groundwater-fed ecosystem; ancient dune ridges push fresh water down and out into the low-lying valleys. This constant water supply is the secret behind the park’s massive biodiversity. Wildlife and Plants of the Great Marsh The Great Marsh is an Important Bird Area (IBA), a stopover for migratory birds. I’m not much of a birdwatcher, but I read that in spring, you’ll find waterfowl, wading birds and songbirds. You can also spot Sandhill Cranes, kinglets, vireos, thrushes and warblers during peak migration. You can find plenty of other wildlife in the marsh, including otters, snapping turtles, frogs and small mammals like shrews and Virginia opossums. For plants, early spring brings marsh marigolds, skunk cabbage, and forget-me-nots. Later in the seasons, you can see pink hibiscus, cardinal flower and rare blue fringed gentian. The observation deck is a perfect spot to bring your binoculars and see what you can find! Practical Tips for Visiting Footwear: Sneakers are fine, but waterproof shoes help if the trail is muddy Ticks & Bugs: Bring repellant and check yourself and pets carefully during tick season Gear: Binoculars, camera (wide-angle + telephoto), hat and sunglasses Facilities: None at the trail or at the trailhead Time of Day: Morning or afternoon is best for wildlife and more dynamic photos Before heading out, check the local forecast: weather can definitely change the feel of the trail. Indiana Dunes National Park Weather After our one-hour hike, we stopped at The Goblin Duneside Bar & Eatery to eat. It’s less than 1,000 feet from the trailhead. Photography Tips for the Marsh Even mid-day in May, the marsh is photogenic. We took plenty of photos from the observation deck, close-ups of mushrooms along the trail and some birds. Mid-day sun like we had can make the marsh look a bit flat, so for more dramatic shots, I’d try shooting during golden hour or early morning. Time for some birding! Mushrooms on the trees Nearby Trails & Trip Ideas Planning a weekend at the Dunes? Find places to stay near West Beach or see hotel options around Chesterton. Both spots make it easy to reach the park’s top trails. If you’ve got an hour and want to explore the wetlands of Indiana Dunes National Park, the Great Marsh Trail might be the trail you’re looking for. We spent the morning at the marsh and later did the Dune Succession Trail to West Beach (dogs stayed back at the Airbnb recovering from ticks). We’d recommend stopping at the Visitor Center to better plan your trip if you only have a day or two at Indiana Dunes. The Verdict: Is the Great Marsh Trail Worth It? The Great Marsh Trail is a great way to explore the wetlands of Indiana Dunes. For an hour, you’re surrounded by birds, mushrooms, native plants and walking paths built over old ditches. It’s a nice contrast to the dunes and beaches just a few miles away. If you’re visiting Indiana Dunes National Park and want a short, dog-friendly, calming hike with birdwatching, the Great Marsh Trail is an awesome, easy walk with an ecological recovery story behind it.
