Cairn II is located on the summit of Pen Cerrig-calch. It measures approximately 20 metres in diameter and roughly 3 metres high. A shelter has been created by hollowing into the centre of the cairn, and this measures 4 metres across and 2 metres deep. The ground cover was bilberry at the time of survey.
