Rocky Knob is a good campground for a couple nights along the Blue Ridge Parkway. Loop C is tent only. Inner part of the loop sites are quite close to each other but have convenient access to bathhouse, which is kept pretty clean. Firewood $7 a bundle on the honor system, but is locked up at 5:30 each night. Great views of surrounding mountains in late October as the leaves fall away.
Spent two nights at Site 67. Nice large site with no other sites behind it and nice distance to neighbors on either side. Camp ground host and park rangers very welcoming and helpful. Wood $5 a bundle from camp host. Self check-in board at camp host site. Completely full Saturday night in September, but lots of empty sites on Sunday night.
