Awesome Au Sable Amble Professional Review and Guide
"Approximately 14 miles of this ride wind along River Road National Forest Scenic Byway, one of only ninety-eight designated scenic byways in the country. It's easy to see why this route would be chosen as a byway. River road runs parallel to the southern bank of the mighty Au Sable River. Along the route on this roads are great vistas, the Lumberman's Monument, Iargo Springs, parts of the Huron National Forest, and the Canoers' Memorial Monument.
This ride begins at one of the highlights of the River Road: Lumberman's Monument Visitors Center. Here are drinking water, restrooms, covered tables, footpaths, Au Sable River scenic overlooks, and a camping area. things to see: River Road National Forest Scenic Byway, Lumberman's Monument, Iargo Springs, Au Sable River."
