Tried to visit 26.6.10.
Failed on this one. I tried to get near the stone via the lane to the west. However, I was confronted by large closed wooden gates with several 'Private – Keep Out' signs!
(I wonder what these type of people are afraid of?) I then tried to get a view from near the newly built houses on the opposite side of the dismantled railway. There is a large field next to the houses which goes right down the railway. The problem is when you get close you come to a 5ft high barbed wire fence and 6ft brambles! There was no chance of getting through that little lot! Judging by the amount of undergrowth I doubt the stone would have been visible anyway?
Mentioned in "The Ancient Stones of Wales" by Chris Barber and John Godfrey Williams (1989 Blorenge Books) as standing on the side of the old railway line - 6 feet high and badly overgrown when visited in July 1985.
Coflein says it is currently of unknown period and 2.2 metres high.
When I tried to visit there was no easy access, and a lane heading towards it was on private property with 'tresspassers will be prosecuted' signs. I gave up and went to Battle Menhir instead.
