It is about the prettiest state park there is.
We live just on the other side of Roan Mountain in Nc, and drive through it lots of times.
Prior to us snow birding, we used to cross country ski all through it and including the camp ground.
The pool is on the same side of the park road that the camp ground is on.
I don't think the camp sites would be good for a large rig.
If you can get a site on the creek you'll love it.
you can walk to the pool from the camp ground.
If you like hiking, drive up to the top of Carvers Gap on Roan Mtn and hike on the AT, or hike out to Roan high Bluff, (6000 feet)
My wife said to tell you that we live on the morning side of the mountain and the camp ground is on the twi-light of the hill !
