Easy to describe - just take Illinois Rte 96 Between Nauvoo & Hamilton.
Fabulous Mississippi River scenic views along entire length of road.
Smooth road surface, slow sweeping corners that hugs the path of the river the entire time. Mostly flat.
There are a few roadside picnic areas along route but other than that, nothing except at the starting point and ending point. If you are into history, there is an interesting and extensive Mormon settlement history in Nauvoo.
