I spent a day at Rock Haven and found it small but relaxing. About 20 acres. The grounds are average. The bath house clean. The pool is small and spring fed so very cold. There is a comminity game/gathering building with a pool table and ping pong table. There are an assortment of cabins from small converted storage building size to some with full ammenities. Small camp ground There is a short walking trail but nothing spactular. Very stony ground so wear something on your feet. Lots of shade. Tennis court. Grill. The people at check in are very kind but all business. They don't take any chances with their guests privacy and comfort. If you are not going to behave yourself, don't go because the guests there are serrious about enjoying the out doors and the company of other people in the nude with no inhibitations. The owner will not hesitate to throw out anyone who brakes the rules.
I was allowed in even though I'm a single male. Many resorts only allow couples and families, no single men. Over all I felt confortable, although striking up conversations with people didn't work so I sat and read by the pool. There was no gawking at women or lude comments heard.
This is not a clothing optional resort. You must be completely nude. Only shoes allowed unless the weather turns a little cool, then only tops may be warn. If you make a big deal about being covered up, you'll be escorted out. It makes others uncomfortable.
Down side is its location. Way out in the country.
I've heard that July 4th is the best time because they put on a kicking fire works show and there are alots of visitors. Also, on Memorial Day weekend and Labor Day weekend, the place is packed.
Rockhaven Lodge is a nudist camp. It is just off Bradyville Pike outside Murfreesboro. I visited it one October afternoon when I was in college. It seemed just fine, if this is what you are looking for.
