We camped here on a Monday night in late September and had no trouble finding an open site without a reservation. The spots were a little close together, but thick foliage in between provided some nice shade and privacy. There was also a nice stone wall at our site to help with erosion control. Good fire pit too. 

Toilets were clean and stocked. 

The Black Canyon Loop trail at the north end of the campground is a great jaunt up to a view of the Santa Fe watershed and the Pecos Wilderness. It's 1.3 miles long and does a lollipop loop allowing for different views on the way up and back - would highly recommend.
