Above the devastation of the Blaenau Ffestiniog quarries is a ridge of hills, reaching to a height of nearly 700 metres. In contrast, on the other side of the ridge lies the beautiful, secluded Lledr Valley, running down towards Dolwyddelan, with the castle and the shapely peak of Moel Siabod in the distance. Today’s walk follows an easy quarry track gently downhill into the Lledr Valley. Leaving the track we pass the remains of quarry buildings, making our way above a narrow gorge and climbing up on faint paths and over rough ground through the higher reaches of valley. Eventually we reach the ridge which we follow over Moel Druman and Allt Fawr, with extensive views in all directions. Our path levels out for a while as we continue, overlooking the town and its quarry workings. Passing the little lake of Llyn Dyrnogydd, we descend the steep grassy slopes beyond to return to the start.
