Winding over Wisconsin's glacial moraines, the trail links together six of the nine units of the Ice Age National Scientific Reserve. It traverses significant features of Wisconsin's glacial heritage. Approximately 475 miles are open to public use; additional miles are being developed.

From its eastern end at Potawatomi State Park on Green Bay, the trail route follows in places the present and former shorelines of Lake Michigan, the crest of eskers, and the edges of bogs in Manitowoc County. In several long existing segments and in many short ones, the trail continues over the rolling upland of Kettle Moraine on public and private lands for more than 100 miles through Sheboygan, Washington, and Waulesha Counties. From marshes to hilltop remnants of prairie oak openings and along waterways through oak, hickory, and maple forest, the trail threads its way among many towns and villages of the densely populated southeast portion of the State.
