Ruined house on the Clwydian Way and Mynydd Hiraethog south of the village of Cyffylliog Denbighshire
Mynydd Hiraethog (also known as the Denbigh Moors) is an upland region in Conwy and Denbighshire in north-east Wales. It includes the large reservoirs Llyn Brenig and Llyn Alwen, and the Clocaenog Forest, which has one of Wales's last populations of red squirrels. Its highest point is Mwdwl-eithin, at 532 metres (1,745 ft) above sea level, making it higher than Exmoor. Moel Seisiog is another 468m (1535ft) summit, which is also the source of the River Elwy (53°05′N 3°42′W / 53.083°N 3.700°W). On its western edge, overlooking the Conwy Valley, lies the Moel Maelogan wind farm.
