When I visited I parked near the farm and took the path past the farmhouse and barns, through the gate into the fields leading to the stone. It was a lovely sunny day and no one was about. This was one of Dafydd's first sites and he loved looking at the animals. The stone is large and is quite easily seen despite being in the hedgerow.
Sampson's Jack is a pointy menhir of white stone which soars out of its hedgerow setting! It is the texture and colour of rice pudding. What a shame you can't see the whole stone – it must be 12 feet tall, but the bottom six feet are hidden in the hawthorn. Without modern buildings it is only maybe 300 metres away from the standing stone at Ty'r Coed farm and certainly on a sight line.
Note for pedants: On the map, the spelling of Sampson has a 'p' in it.

Majestic against the setting sun over the Gower hills, we got to this stone having missed it when we previously visited Arthurs Stone (Maen Cetty). Samson's Jack is on farm land just over a hedge/gate which we chose not to cross as we were being 'buzzed' by a local farmer in his van, he was probably friendly but we didn't get a chance to say hello.
