Discontinuous lengths of banking on the southern slopes of Cefn Drum, suggesting the vestiges of an enclosure, lie on the south side of a track which climbs the nose of the ridge.
There are two distinct elements. The first follows a roughly NW-SE line for about 25m from the track, stopping 10m short of the second bank. This a reverse L-shape on plan and measures about 9m (NNW-SSE) by 9m. Both banks are overgrown with heather and bracken and are spread to 2m wide and rise to no more than 0.4m. Platforms, cairns and other banks lie in the vicinity.
