Visited 25th May 2004: To the east of the Cwm-y-Saeson stones is Henriw Standing Stone, a full metre taller than its neighbour but much less accessible. We spotted it from the road, which is probably as close as you can get to it without approaching a landowner. It’s behind a field boundary, so you have to find a spot where there’s enough of a gap in the foliage to see it.
Like the anorak that I am I had binoculars with me, which turned out to be useful (the stone is about 300 metres from the road). Must come back when I have more time and see if I can get a closer look.
