To the south of Benderloch village. Alongside a private road.
Now, here's something you don't see very often in Scotland, a sign which says 'Private - no entry'. But that is what it says on the sign at the start of the road. (Perhaps the people who live there are originally from southern England :))
Karen parked at the start of the road whilst I duly ignored the sign and walked up the road. The large stone is located in a field to your right near the house.
There is a fort the other side of the house near the shoreline but I didn't push my luck that far!
The fort is called Dun Sniachan (NM90323822)
The stone measures 2.1m in height by 1.2m at the base. Local tradition states the stone once formed part of a circle. Two stones were recorded in 1772. Buried stones are said to be burried 60ft south of the stone.
