Jackson's Portage Lake Loop Professional Review and Guide
"Some of the prettiest country roads in Michigan are on this ride. If you don't like one stretch, just keep pedaling, and something different will soon appear around one of the many curves. The terrain varies from flat to rolling hills to flat again, offering variety every other mile or so. At the sides of the road, you'll find marshes, creeks, ponds, and lakes. There's also a lovely mixture of evergreens and deciduous trees.
Two nice places for picnics or breaks are the Portage Lake Unit of the Waterloo Recreation Area, on the southwest side of Big Portage Lake, and the Jackson County Park, on the east side of the lake. Things to see: Portage Lake, Waterloo Recreation Area, Jackson County Park, wide range of scenery."
