I explored the Huron Mountains of Michigan’s Upper Peninsula in late September a couple years ago. I drove my Jeep Wrangler in a 200-mile loop that started and ended in Marquette Michigan while stopping to do several day hikes. The northern section of this route from Eagle Mine to Lake Roland below Mount Arvon is forest service roads/trails. I wouldn't recommend trying it without a high clearance 4-wheel drive and a good GPS.
Sandy and muddy trails of Michigan hold the evidence of those that walked there.
