We hiked up to Juniper campground from the Clayton side. The sites in the teens have less overhead shade but more privacy than those of higher numbers. The sites closest to the driving road/entrance/overlook will have the potential to be downwind of the bathroom, unfortunately.

The campground is a dry campground - as in no alcohol.

That said, we loved our site #15, and enjoyed the privacy it provided, plus the views (if you stand on the table or are tall). We didn't encounter critters. We had some trouble staking down on the rocky dirt. 

This is a good campground to explore the rest of the summit areas, plus Rock City.
