About Coety Mountain [Coity Mountain] [Mynydd Coety]

Rising as a broad, flat-topped massif between Blaenavon and Abertillery, this Marilyn marks the highest ground for both Torfaen and Blaenau Gwent. Its scarred terrain reflects a deep industrial heritage, with the Big Pit mine workings running directly beneath. The plateau offers clear views across the Usk Valley to the Sugar Loaf.

Did You Know?

• •The Welsh name Mynydd Coety likely stems from 'coed' (wood) and 'tŷ' (house). While it suggests a wooded dwelling, the modern landscape is a stark, high-altitude moorland shaped by centuries of heavy industry.
• •The mountain is a central component of the Blaenavon Industrial Landscape World Heritage Site; the labyrinthine tunnels of the Big Pit National Coal Museum honeycomb the ground deep below the summit plateau.
• •A short walk southeast of the main ridge leads to the 'Dog Stone', a lonely memorial marking the spot where a Red Setter named Carlo was accidentally shot by his master while hunting in August 1864.
• •On a clear day, the summit offers a commanding perspective over the South Wales Valleys, with the distinctive limestone escarpments of Mynydd Llangatwg visible to the north and the Brecon Beacons beyond.
• •Despite being the highest point in two different counties, the summit is so remarkably flat that you may find yourself pacing the heather for some time just to be certain you have reached the actual high point.
