Park at the top of the lane by the farm entrance and ask at the farm to see it, because this is on private land.
The farm building is only inches away from this menhir which is made of the same rice pudding stone of Sampson's Jack. Because it stands in a rise of land its size is deceptive. It must be at least seven feet tall. From here you get a very clear view of Maen Cetty on the ridge to the south about a mile and half away.
The stone is kept in a small enclosure with three dogs so mind where you tread - it's very shitty!
