Illinois’ highest spot and the 45th highest US state summit, 1,235-foot Charles Mound is located in Illinois’ northwest quadrant, west of Rockford, and close to the Wisconsin border. With only 95 feet of prominence, Charles Mound is an unranked summit, and is far down on the list of the most prominent peaks in Illinois. This highpoint is on private property, and access is limited to the first weekend of June, July, August, and September. This highpoint requires a walk up a road to reach the highest ground that is near the house on top of Charles Mound. This highpoint is wheelchair accessible, probably with some assistance.

To get to Charles Mound by car, go to the town of Debuque, IL, and go 28 miles west on State Highway 11. If you are in the town of Monroe, WI, go 27 miles west to the town of Shullsburg, WI, and turn south on WI County Road O. Go 3 miles on CR O, and pass a sign that says that Scales Mound is another 4 miles. CR O will then cross into Illinois, and the road is renamed at the border.
