This linear state park begins in Comstock Park, 12 minutes north of Grand Rapids, and runs 92 miles north to Cadillac. The majority of the trail is natural ballast and hard-packed gravel, but two segments are paved with asphalt (13 miles from Reed City to Big Rapids and 7 from just north of Rockford to Belmont.). The Belmont trailhead, 15 minutes north of Grand Rapids, offers ample car parking.
