Been awhile since I have been there but I think the two or three loops are not too bad... You can tell the original camp sites were built for tent camping sites haha...
This meaning you park along the road and walk into the tent pads area etc...
Here is the official site link... Hope it helps... Check the map section...
COSBY CAMPIf the tree cover will permit you might be able to spot your assigned site from GOOGLE search... This doesn't work for the camp sites at ELKMONT however. Can only see the site road in a couple of places using SAT VIEW there...
