Description from Coflein:
“Remains of a burial cairn, situated on the NW-facing slopes of Carreg Lefain. The heather-covered cairn is circular on plan and measures about 11m in diameter and up to 0.75m in height. A well defined kerb of large stones is visible around much of the perimeter and two larger upright stones stand within the cairn.”
