Cwmcuttan is an adult only C&CC CS site well worth a visit if quiet seclusion is your thing. We enjoyed a restful week long stay there while touring the Brecon Beacons during June 2018 in spite of the dull weather we encountered.
The sense of seclusion is heightened by the absence of telephone and television signals, although I was able to get my daily news fix via the excellent site wifi system. It’s a basic site, so your own facilities are essential.
The pitches are all hard standing with electric hook-up and well spaced around the large site. Those of us with dogs will appreciate the extensive mown footpaths through the adjoining large field.
