Don't miss the chance to see Cowles Bog, one of the great natural areas in the Indiana Dunes National Lakeshore. Remnant of a once-widespread wetland system, Cowles Bog encompasses a marsh surrounding a small fen, where a stand of tamaracks and white pines grows on a floating mat of peat moss. Starting near the guardhouse in the northeastern part of the site, a boardwalk trail passes marshes and ponds that host horned grebes, black-crowned night herons, buffleheads, and a myriad of other water birds. You can hike right out to the beach and back on 4.5 miles of interconnecting loop trails. Two trailheads serve the trail system, each with a portable toilet.
