I used to live in blue ridge. Most of there country dirt roads could be classified as Jeep trails. Lol. But if you cross the border into Tennessee, there are tons of off road trails going up bluffs and overlooks, and also lots of old logging roads. No official off road parks that I remember, but me and my 4x4 truck never had a problem finding a dirty muddy dirt road to get kit off road fix on. Just drive around the countryside, and keep your eyes open for dirt roads. Mudding is a popular local hobby, so you could ask the locals where the best spots are.
