Turn off of the A5 onto the A5114. Turn right after 1/4 mile down a farm track to Lledwigan farm. The stone lies in the middle of a field behind the farm just after the track bears right. Access to the field is by climbing over a large iron gate. With a dodgy knee, an anxious looking bull, and no farmer to ask, I unfortunately couldn't get close enough to take a decent photo. Difficult to get depressed about this when Bryn Celli Ddu is the next location on my list!!
