Discover waterways crossing Indiana Dunes

Only one river flows through Indiana Dunes National Park, but a couple of streams do make their way across the park, one as a tributary to the East Arm Little Calumet River and the other flowing directly into Lake Michigan.

Here are some great day trails to discover those waterways:
• Dunes Creek – The 4.3-mile stream drains the Great Marsh and then West Branch (which in turn drains Cowles Bog) passes through coastal sand dunes and flows into Lake Michigan at Indiana Dunes State Park. Good trails to experience the creek are the Calumet Bike Trail (between Tremont Road and East State Park Boundary Road) and Trail 2 in the state park.
• East Arm Little Calumet River – The 22.1-mile long waterway has greatly changed since the arrival of Euro-Americans. Before 1926, the stream used to connect to the Little Calumet River in Illinois, but that year construction of the Burns Waterway diverted the route so it drained into Lake Michigan at Burns Harbor in Indiana (which can explored at the Portage Lakefront & Riverwalk). One of the few undisturbed portions runs alongside the Little River Calumet Trail. Park in the lot at the end of Howe Road south of Oak Hill Road/County Road 1350 N. Take the trail 0.9-miles one way west to a bridge crossing the river as well as 0.3-miles east toward the Bailly Homestead.
• Salt Creek – This 24-mile tributary of the East Arm Little Calumet River flows north from Valparaiso, Ind. The Indiana Department of Natural Resources regularly stocks the creek with steelhead trout, Chinook salmon, and coho salmon. No park trails cross Salt Creek, but both the Iron Horse Heritage and the Prairie Duneland trails just south of the park do.
