Michigan Department of Natural ResourcesThe Iron Belle Trail is the longest state-designated trail in the U.S., spanning over 2,000 miles from the western Upper Peninsula to Belle Isle in Detroit. The trail is currently more than 70% complete and connects over half of Michigan's counties. This unique trail features two distinct routes: a biking route and a hiking route. The biking route travels along the eastern side of the state, using existing bike paths, lanes, and designated routes. Meanwhile, the hiking route follows the western side of the Lower Peninsula, incorporating sidewalks, trails and a significant portion of the North Country National Scenic Trail.
