- At the confluence of the Illinois and Mississippi rivers is a stretch of road officially known as "Meeting of the Great Rivers scenic byway". It was chosen to be one of the seven wonders of Illinois. In Grafton it is better known as Main Street. The town runs long and narrow, with limestone bluffs on one side and the Mississippi River on the other. Valley View Inn sits at the western edge of town just seven miles from the Lodge at Pere Marquette State Park. Check us out at .graftonvalleyview. We may be right for you.
