There are no resorts in KY. It's not against the law to open a resort here but the law makes it VERY difficult and most people won't put in the time and money it would take to get one started. There are a couples resorts in Indiana and TN, as well as Ohio. I usually attend Paradise Gardens in Cincinnati, but would like to try out some in IN, like Drakes Ridge.
I do know of a park in Taylorsville, KY that I can go on nude hikes some times. There's only one way in/out so if no cars are there, and usually there aren't except hunting season, then you are at least safe hiking in nude but must be careful when you go to leave... lol.
