Busy Central Illinois Campground on a lake
This is our go-to campground when visiting the U of I. It is a large campground with well spaced campsites for tents and rvs. Almost every site has plenty of shade with lots of tree cover. This also means in the dog days of summer the breeze is blocked by the trees so get an electric site even with a tent and bring a fan. They have a beach and a boat launch. The loops that allow alcohol can get a bit rowdy with weekend partiers, but the alcohol restricted loops can get loud from all the families. However, with full hook-up options there is no generator noise. The showers/bathrooms are kept up well given the massive amount of people served. If you own a boat and camp, this place is ideal for central Illinois.
