Cumberland Gap Natl Park
We have been at this park for about a week and plan to stay through the holiday weekend.
The campground is very nice, clean and especially quiet. The sites are spacious and lush with trees and vegetation (and also some poison ivy). There are electric hook ups but no water at the sites. It is first come, first serve no reservations but there seem to be plenty of available sites. There is no pool or playground and not many kids but there are tons of hiking trails and lots of historical things to see.
The campground is in Virginia. The town is in Tennessee and the park headquarters is in Kentucky. There are two state parks which are very close by. Wilderness Road state park is a Virginia state park and they have an excellent reconstruction of a 1700s settlement complete with live re-enactors. The Kentucky park is Pine Mountain and it is beatific with a nature center, a huge petrified wood tree and the legendary "chained rock".
We discovered that Middlesboro, KY was formed by a meteor and also has no sales tax on food but appears to be a dry county.
There is a cave tour that we plan to participate in later this week. The national park also offers a half day tour to a 1700s settlement village. If you go to this park make sure to take time to watch the videos at the park visitor center.
My overall impression is that the park is very much like the Smokies without all the traffic and congestion. If you like history, hiking and beautiful scenery you would enjoy this campground.
Be aware that the Allstays app describes the campground as having full hookups but it only has electric at the sites. There is a dump station and a place to refill clean water. The bath houses have two private shower rooms each and are very clean. RV sites are paved and large with a fire pit, grill and picnic table.
And best of all if you are 62 or older you can camp for $10 per night.
