At more than 500 metres above sea level, descending on foot from the remote summit of Garn Felen, it's rather surprising to come across a concrete lamp standard. It once helped to illuminate access to the upper quarries of a complex that may be reached via progressively rougher roads from the signpost to Trefil, off a roundabout on the A465 'Heads of the Valleys' road. In this area there is an interesting juxtaposition of the abandoned limestone quarry workings and the natural beauty of the distant central Brecon Beacons ridges.
