I visited this site about two years ago.
As you drive along the lane which runs next to the stones, there is one stone to be seen amongst the undergrowth. To get to the stone you need to climb over a fence and scramble up the bank. This isn't too difficult if you are reasonably mobile. If my memory serves me right there is barbed wire on top of the fence. The stone has fallen and I couldn't see the other stone which is recorded. It is possible it was in the undergrowth somewhere?
Pair of standing stones 40m apart, lying in small piece of woodland on the east side of the road running N-S from Llanbedr to Llangenau, in the Grwyne Fawr valley.
The northern stone is 1.88m high, the southern 0.84m high. However, it appears from Coflein that the southern stone may have been destroyed.
