Cedar Hills Campground Wisconsin
I was wondering about this place too. I was researching it online and I saw a lot of sites that were advertising it as a campground but they weren't saying anything about it being a nudist campground. I'm curious to know what it's like as well. If you find out any more information on it you should PM me.
Cedar Hills is listed in the Locations sections her on TN. There are a couple of reviews from 2019 but not much more than that. The link to the campground's web site did not work. There are multiple people who listed themselves as members on that location. You could try sending some of them a PM and see if they have any recent information. You could also call the campground office and ask. If you do make a visit be sure to write up a review.
