If you're coming from Cataloochie then the campsite is a two mile hike, about a third of a mile past the point where Palmer Creek Trail turns off to the left over a half-log bridge. The hike is all uphill toward the campsite, but not obnoxiously so like some other local hikes. When I was there today there were about 12 tents and each had all the room they wanted, with plenty of prime spots still open. The area would easily hold 50 tents if everyone was friendly. There are maybe four or five fire pits. It's surprisingly flat and open considering the surrounding area. The grey dotted line trail on Google Maps is Palmer Creek Trail, but Pretty Hollow Gap Trail will take you right to the campsite. Since there was no grey dotted line on Maps once Palmer Creek turned off, I thought I'd have to watch out, but I was watching for a turn and then I was suddenly right there at the campsite. The most scenic part of the hike is the stream, which is gorgeous with several places to step off the path and enjoy. This particularly seems like the perfect place for a big group camp out. There's lots of room for people to spread out.
