Fox Den is a loop located in the Chain O'Lakes State Park. These sites are standard by definition, but the land they sit on ain’t no mediocre. These grounds are located right in the Namaskar, heart center, of Illinois’ largest group of lakes, making this spot every water lover’s wet dream. 6,023 acres alone can be explored for campers—bike, hike, horseback ride, picnic party or hunt—then return to your cozy campsite for a starlit night. We’ll tell you where to sign up.
