Laggan Cairn (Barrhill) is located in a recently planted forest c. 1.3 miles ENE of Barrhill, a village in South Ayrshire. Laggan is a ruin on Forest Road off the A714. The sub-circular cairn is on a slope with a grassy perimeter running from NW to SE up to 1 yard high. The central hollow retains several stones surrounded by ferns. I estimated the diameter of the cairn to be 18 yards. This corresponds to the 16 yards quoted in Canmore 62530.
