Visited 8th August 2003: Parc y Garreg is not visible from the road because of an enormous hedgerow. The field it stands in is not directly accessible from the road either, but is adjoined by a field that has a gate onto the road.
The stone stands close to a hedgerow that runs north-south, and when I visited it was surrounded by cattle. One heifer called 1-93 seemed to be particularly fond of the stone, and was clearly reluctant to budge just because I was there. Making the best of the situation I decided she would provide me with some scale for my photos (after all she did get there first).
