With a rainstorm raging and under the watchful eye of some rather large Highland cattle we found the Tordarroch ring cairn. It was very helpful to have a 1:25000 os map to find this clava ring-cairn. The outer stones, with a diameter 113ft and with 7 of the 11 visible stones still standing (graded to the s-sw), make this an impressive site; although the ring-cairn is in a sadly ruined state. The inner face of a fallen curb stone in the s-sw of the ring-cairn has 30 cup marks carved into it. Worth a visit as a 200yd walk will get you from the roadside to the centre of the circle, but it is also easily viewed from the road.
