We had a great time on the Cain hallow loop site 18. The satellite pictures do not give away how hilly the terrain is on the loop. We were at the top of the hill with a great view.
We did not expect to have zero cell phone reception, t-mobile, but turned out to be great as we just enjoyed the views and the time at the fire .
Our site had a huge space for the kids to run and play.
The bathrooms were clean and cleaned frequently while we were there. We saw the ranger or park staff drive through once or twice a day and they always waved and were friendly.
Lots of things to do in the park and explore. Definitely planning to go back again!
