Barren has a nice little campground just off of the water across from the state park. Spring Hill Rv Park. It is open year round with full hook ups. The price is right and everyone is very friendly.
I have had my RV there for the past two years and so has a brother of mine.
I do not know of any place on Nolin or Rough like it.
