If you went on the other side of the mountain range in the Gatlinburg/Smokey Mtn Natl Park area they have a couple of nice waterfalls you can hike to. Also have several hiking trails... We always camp at ELKMONT camp that only has water available from a spigot outside each of the bath room buildings... When we camp at ELKMONT we always go to the Townsend town for supplies and groceries etc... Galtlinburg and Pigeon Forge is always a pretty hetic town with lots of traffic...
They do have a RV dump site at the entrance to the Smokey Natl Park.
Crossing the mtn from Cherokee might be abit much for the longer trailers. We don't have any problems doing the mtn road with our Popup trailer...
