Off the beaten path, most people who come to this area will likely go to the much larger and better known Rock Cut State Park. This is a small forest preserve with lovely picnic areas, a picturesque creek and an outcropping of bluffs ( about 3 storeys tall).
 The campground is well maintained, with the cleanest pit toilets I've ever seen. (also ADA accessible).
 There are about 40 sites, ranging from primitive tent to full size pull-through RV.  30 and 50 amp elec available. Prices based on what you choose. Reservations are recommended a week ahead through the Winnebago County Forest preserve website. There is a small fee for non-residents, but it's worth it.
 we went in November, so I can't say what it's like during peak season. But sites are well spaced, though they are all open to each other visually.
 Nearby are bike trails and the Pecatonica river, with other forest preserves for day trips out of the camp.
 This is one of three campgrounds run by the county. We have stayed at another, Sugar River, and enjoyed it as well.
