Trefil
Wales
Trefil is a former quarrying village perched in the Blaenau Gwent hills, reached via the A4048 from Tredegar and connected to the A465 Heads of the Valleys Road. The dramatic terraced quarry workings carved into the hillside create a distinctive amphitheater visible across the Sirhowy Valley.
