I knowledge of the geography of North Carolina and West Virginia is somewhat limited so I'm not sure how close any of these places are to where you'll be but here are some trails to check out:
Tsali - beginner friendly, 4 really nice loops, nice scenery, can't get lost
Pisgah - huge area with tons of different trails ranging from mild to death march climbs and white knuckle descents
DuPont Forest - Kinda like a mini-Pisgah, the climbs aren't as big and descents not as long, but lots of fun
Snowshoe - Lift-accessed riding, leans more towards DH/FR than XC.
I'm sure there is much more in WV, but Snowshoe is the only place that I am familiar with.
