The campground in the southern unit at Illinois Beach provides 241 Class A Premium sites with electricity and access to showers and sanitary facilities. You must obtain a camping permit from the park staff, and must have a camping unit upon arrival.
The campground is open from April 1 through December 30. Reservations can be made up to 180 days in advance at ExploreMoreIL™. Reservations are only accepted from May 1 - September 30. Due to the high use of this area on holiday weekends, reservations are recommended. Campsites also are available on a first-come first-serve basis, but understand that the campgrounds fill up early on Fridays during the summer season. Six handicap accessible campsites are present in the campground near the accessible restrooms and a dump station.
