If you approach Council Grove Reservoir from the west via the Kelso Road you come across a barely marked wildlife viewing area. The roads here, as many in Kansas, are minimum maintenance so it may be that you park your vehicle and walk into the area if the roads are questionable.
This area is along a couple of bends in Munkers Creek. It is beautiful in summer as well as winter and is a great habitat for a wide variety of birds, including hawks, woodpeckers and cardinals. I've seen tracks of deer, racoons, and other small animals in the area but have not ever actually seen any of these creatures.
