What to Expect

This short loop drops you into one of the most underappreciated ecosystems in the national park system — a freshwater marsh tucked between Lake Michigan's dunes and the industrial skyline of northwest Indiana. The trail is dead flat and follows a mix of boardwalk and packed dirt through cattail stands, sedge meadows, and shallow pools that attract an absurd variety of birdlife. Great blue herons stalk the shallows like they own the place, and during spring and fall migration, warblers move through the canopy in waves. The landscape feels more Louisiana bayou than Midwest, which is part of the charm. You'll finish the loop in well under an hour, making this an ideal warm-up or cool-down paired with the nearby dune climbs. Birders and anyone who appreciates quiet, overlooked corners of a park will be in their element here.

Safety Advisory

Mosquitoes are relentless from late May through September — long sleeves and DEET-based repellent are non-negotiable unless you want to donate a pint of blood to the marsh ecosystem.

Boardwalk sections can be slick after rain or morning dew. Watch your footing, especially if you're scanning the treetops for birds instead of looking down.

Pro Tips

Trail Tip

Arrive within the first hour after sunrise for peak bird activity — the marsh comes alive before the foot traffic picks up, and you'll hear species you'd never spot in midday heat.

Trail Tip

Bring binoculars and a lightweight field guide or birding app. The marsh regularly hosts species like Virginia rail, sora, and marsh wren that most casual hikers walk right past without noticing.

Trail Tip

Pair this with the Cowles Bog Trail nearby for a half-day combo that covers wetland, dune, and lakeshore ecosystems — three completely different worlds within a couple miles of each other.
