A cairn is located on an outcrop scarp of a low rise above the west side of a tributary stream of Nant Melyn.
It measures 8.5m in diameter and 1m high. The mound is composed of loose limestone blocks and has a pronounced hollow at its centre which measures 2.5m across and 0.75m deep. On the immediate south a length of right-angled walling has been built, perhaps from cairn stones. It measures 5m (NE-SW) by 7m (from the south end), 0.5m wide and 0.2m high. The longer side is largely overgrown with heather and grasses.
