Garn Ochr Cairn is a greatly disturbed and much denuded round cairn some 21.3m in diameter and surviving to only 0.5m high. It was contained within a ring of thirteen ORTHOSTATIC - earthfast - stones, although only ten remained in 1966, two of which were prostrate. The stones are up to 2.0m long.

This is probably a prehistoric funerary or ritual monument. It has been supposed that there was originally a burial chamber within the ring although there appears to be no evidence for this. Three stones, now gone, some 12m to the north-east, were seen as evidence for a burial chamber.
