The North Central State Trail is not only one of the newest recreational trails in Michigan but the longest improved rail-trail, stretching 61.9 miles from Gaylord to Mackinaw City. Much of it is like any other rail-trail in northern Michigan; a flat, easy ride along a crushed limestone surface through woods and farms and pass trout streams.
