The Davidson is a freestone stream. Be aware that this time of year people are swimming, tubbing, and generally enjoying the same water that we want to fish. I think you would be better off somewhere less popular. Balsa Mountain is a nice camp ground, and the elevation keeps it cool. There is a campground on the parkway across from the Pisgah Inn that is nice. If you go to Cataloochee during the week you can generally find a site, especially if you go in on Sunday or Monday.
