Yes, there are several camping locations and a shelter in that area.
Small campsite about 0.5 miles in. Another at 1 mile. Several around the shelter at about 2 miles in. There was also a few possible places to set up a tent around 4.7 miles in near a creek, but it wasn't a designated campsite.
I do video virtual hikes of various trails and I have started the Pinhoti. It is a virtual hike and I am never in it, but I show the trail iteself, the campsites, the shelters, water sources, confusing intersections, views, etc. It has trail descriptions and mile markers. It is all about the trail. If you are interested, you can take a look here:
