A great view of Snowdon sitting over the Nantlle Valley

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.

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.
