On Mynydd Illtyd 8km west of Brecon and 1.6km Southwest of Brecon Beacons National Park Mountain Centre.
Situated in the gap between the two halves of Glasfynydd Forest.
Middle of nowhere.
In 'Prehistoric Breconshire' by Children and Nash, Logaston Pr. the name of the stone is given as: Troed Rhiw Wen.
At the farm buildings Caerllwyn, head up the single lane tarmac track with a no through-road sign.
About 1km west go through a gate across the road, 200m later go through another gate.
Over the small bridge and through a gate into the yard of Blaenau Uchaf farm.
A bridleway runs up along side the farm house (access through a gate).
Follow the bridleway in an uphill curve to the left.
When near the top look into the field up to your left and the stone will be in the upper field 100m or so away.
The stone reminded me of a smaller version of Maen Mawr (6km or so to the south), a large block of sandstone stood on its longest side. It appears to be raised on a grass covered stone cairn.
(Dimensions given as: height 1.68m, breadth 1.3m and thickness 0.94m)
