Work on the Iron Belle Trail continues, with about 71% of the trail complete so far. When completed, the Iron Belle will cover 2,000 miles around Michigan and will be the longest state designated trail in the U.S. The Iron Belle consists of two trails, one for hikers and the other for biking. The hiking trail will be 1,204 miles long and the bike trail will be 828 miles long when completed. The Iron Belle Trail will connect 48 counties and 240 townships across the state. Most of the hiking trail will follow portions of the North Country National Scenic Trail.
