Campground facilities were the cleanest I've ever seen! The bathrooms and showers were cleaned at least once every day, and were in excellent working order. Our campsite was clean and had everything we needed, and the camp hosts were friendly, informative, and helpful.
This is an excellent camping spot if you want to do the hike up to the top of Mt. Mitchell like we did.
One tip: be prepared to keep your camp site clean and store all food and scented items in your vehicle due to bear activity in the area. We were given extra warning about this upon check-in. We took it seriously and had no problems with bears though.
