Gwynedd, Wales.
The OS map indicates 4 stones in the row, only two are highly visible & with the amount of debris from the nearby wall it is difficult to distinguish which these could be.
It's a wonderful walk, a tough start with an uphill climb from Llwyngwril, the rest is quite flat all the sites are accessible. There is a steep downword trot with a bit of searching you can also find the Arthog stones.
