My wife and I are looking for a clothing optional camp site somewhere in the Midwest (300miles radius around central Illinois). The place we normally go to in Iowa is a nice private little camp site that we found on Hipcamp that is clothing optional and only has 3 tent camping spots. Very private and even if you end up a neighbor or two they’re going to be naked too. Unfortunately a group has booked all three sites for one of the days we wanted to go camping there in a couple weeks.

Does anyone have any recommendations for a secluded, small camp site where we can run around naked, enjoy adult activities outdoors, and have few if any neighbors?
We’re willing to travel up to about 3 hours from central Illinois. We are considering a nudist resort like Sun Aura in Indiana but not sold on the idea of so many people, plus we’d like to enjoy sexy time outside our tent, which I understand is frowned upon at Sun Aura.

Thank you!
