Waen Ddafad cairn is a centrally disturbed kerbed cairn, 11-12m in diameter and 0.6m high. An excavation in 1973, showed that the much-robbed cairn covered a central, rather ill-defined pit, 2.9m by 1.7m, containing traces of a possible cremation. The finds included a whetstone and a small ceramic fragment.

2. Following excavation, the cairn is visible on the ground as a series of large stone boulders defining the kerb of the cairn and two stone boulders marking the position of the central pit. No other cairn stone survives.
