Chain O'Lakes State Park in IL has two electric campgrounds, 2 non-electric campgrounds and one group site.  Fox Den is superior to Honeysuckle Hollows because each site has an individual electric post.  Sites in Honeysuckle have electric posts to far from parking pad.  Fox Den also has more space between sites, more level pads and each site is tucked away with trees.   In Honeysuckle you will have  clear line of site to very close neighbor. 

There are three campgrounds close together, Fox Den and two non-electric campgrounds Turner South and Prairie View that share the bath house which was clean and  is in the  center of them all.

There are hiking trails and this campground is the closest to the  boat dock and concession which serves as the camp store.
