We spent 8 days in the campground. The host was excellent and clearly there to make the stay pleasant. Each site has electricity and access to water. Some have more.
All the hiking in the park is some of the best in Illinois. The visitors center has a lot of great information. The lodge has some of the best fried chicken anywhere and is very reasonable. Saturday night the dining hall was packed because of the all you can eat venue not to mention the excellent service
This is a park that would be better labeled as an unforgettable experience.
