We stayed at Gulpha Gorge while spending a day of our road trip in Hot Springs. We arrived later than planned at about 10am, and there still were several spots available. We chose the very first site next to the entrance as it was by the creek and had a  nice white noise. The bathrooms were clean and what you would expect from a Parks Service bathroom. The camp hosts were excellent and very helpful, particularly in navigating the unusual reservation machine they have. All around a good base camp for the area.
