Rend Lake, IL, located in the heart of southern Illinois, is a natural haven for wildlife and a recreational haven for visitors. Rend Lake consists of 18,900 acres of water and 20,000 acres of land. Campers will delight in the nearly 800 sites found in 5 public campgrounds on Rend Lake.
Reservations for Rend Lake are made through Recreation.gov. In peak season, the most popular campgrounds are typically claimed within minutes of each release — which is why the park reads as "sold out" for most of the year.
Sold out is not final, though. People book far ahead and plans change, so cancellations return to the official calendar throughout the season — with no announcement, at any hour. A cancelled site is bookable by whoever sees it first.
