Looking for some recommendations on campgrounds in the Smokey Mountains. It will just be my wife and I for two weeks. We like quiet campgrounds, larger sites so we don't feel right on top of the next camper, don't need a whole lot of campground activities, with trees and ideally near water. I've been looking and so far, Orchard Lake in Saluda, NC, Happy Holiday and the Cherokee KOA in Cherokee, NC seem to look OK. Any comments on these , loud trains or anything like that? Any other suggestions are welcome, doesn't have to be that exact area, it's just where I've been looking (wife wants to visit Biltmore). Thanks in advance.
