June 25, 2024, View of Snowdon (Yr Wyddfa) Across Llyn Nantlle Uchaf

Nantle Valley is well known for its mountains and ridge. A lot of historic settlements and slate mining. Stunning views of Snowdonia. Road surface is good watch out for sheep moving freely and a couple of cattle grids in this area

Llyn Nantlle Uchaf is a gorgeous little lake in the tranquil Nantlle Valley. It used to be one of two lakes here, however the lower lake was drained to protect the slate quarries. It was the subject of a famous 18th-century painting, 'View of Snowdon from Llyn Nantlle' by Richard Wilson, and is also the main setting of the fourth branch of the Mabinogion, Britain's earliest prose stories.

Gloriously situated on a rugged upland common between the modest summits of Moel Tryfan and Mynydd y Cilgwyn, Y Fron is a peaceful Snowdonian village. There are some fantastic hikes from the village onto the 'Elephant Mountain' of Mynydd Mawr and on the sensational Nantlle Ridge. The village's community centre has a shop, cafe and offers accommodation. See canolfanyfron.org for more information.

In the heart of the secluded Nantlle Valley, Dorothea Quarry's slate veined pits and deep, dark pools silently remind all who wander by of the region's mining heritage. Six pits remain, the deepest dropping 348 feet (106 m) below the surface. Quarrying ended here in 1970. The pits constantly needed pumping in order for them to stay dry. In 1904, a Cornish beam engine was installed, which today is a Grade I-listed building. Its operation ceased in 1951, when it was replaced by electrical pumps.

You are likely to have heard of the Nantlle (pronounced Nant-lee) Ridge, a sinuous and wonderful traverse of medium-sized peaks to the south west of the Snowdon Massif. The ridge is named after this little village to the north west, which has its own little llyn (lake) and a proud slate mining heritage. The Nantlle Valley is beautifully secluded and undoubtedly scenic. It's thought that around 85% of its population still speak Welsh as their first language. Accommodation can be sought at Trigonos B&B.
