Visited 2nd June 2004: Just wanted to check on the stone as I'd not been to see it for two years. It was a lunctime dash, and my mate from work tagged along for the ride (hence the shirt and tie).
Visited 26th August 2002: The Cwmere Farm Stone is off the beaten track, on a loop road that runs from the village of Cwmere to Bont-Goch. You can approach it by car from either end, but from Bont-Goch the road is gated.
The stone is marked on the Ordnance Survey map, so it's not too tricky to find. You can see it from the road (on the right coming from Cwmere) and there's just about space to park a car (in a passing place opposite the gate to the field that the stone is in).
There's no footpath to the stone, but we decided to exercise our right-to-roam (perhaps a bit prematurely), and take a closer look. If you decide to do the same, please act responsibly, and be courteous to the farmer if he turns up (I'm probably preaching to the converted here).
The stone itself is striking, with a distinctive taper to it. There are smaller recumbent stones nearby, but they don't appear to be positioned in any way.
