Found this on our way to Colorado from Michigan and what a Gem. We don't like crowded campgrounds and happy to give up some amenities to have some elbow room, peace and quiet. No water hookup but spigot nearby. No sewer hookup but dump station on-site.
So fun to hike and explore a series of canyons along the Illinois River. Nearby Ottawa has all the city amenities and nearby Utica in the opposite direction a quaint strolling town, bike paths. Will return!
