While it's rough getting to Dolly Sods wilderness, the campgrounds themselves are easy to get to themselves, and it's just a short walk to the Black bird Knob trail with other just a short drive away.
There's only 12 sites on the ring and no attendant to take payments for sites only a board at the entrance with pay envelopes for cash or check and a spot to drop off envelopes. Never saw a park ranger while on site but it's orderly and clean and the vault toilets had plenty of toilet paper stocked in them. Just don't expect being able to restock supplies at a lil store on site and you will be good to go.
