This fort is very easy to spot when heading down the A849 towards Iona. It is a large rock outcrop. Unfortunately I didn't have time to stop.
On the summit of a rocky knoll situated 350m N of Torrans farmhouse, between the road and the shore of Loch Scridain. The remains of the Dun measures 30m x 14m. The wall of the dun is now reduced to a grass-grown band of rubble about 0.3m high. The only feature within the interior is a modern stone-walled enclosure. 1972.
