1. SAM No CN358
Two large cairns, probably dating to the Bronze Age and situated within open moorland on the summit of Y Garn. The stone built cairns are circular on plan and measure about 10m in diameter and up to about 2m in height. The cairns have both been disturbed in the past, with the construction of drystone shelters around hollows dug into the centres. Cairn A is the easternmost cairn (SH551526) and Cairn B is the westernmost of the pair.

2. 'Cairn A (the easternmost) has an arrangement of stone slab seats, forming a ring around the scooped-out interior. Cairn B is much smaller and has no obvious seats within the central hollow. North of Cairn A there is a shapeless pile of stones, apparently the remains of a modern way-finder cairn; however, it appears to occupy the site of a despoiled third cairn here, marked by a low, semi-circular stony bank enclosing the headland at the very edge of the precipice.'
