Deiniolen is an electoral ward and village in Gwynedd, north‑west Wales, sitting on the lower slopes of Snowdonia with good views towards Snowdon. It lies close to the great slate works of Dinorwig Quarry and the pumped‑storage Dinorwig Power Station, and is within easy reach of Caernarfon and Llanberis, so tourism and commuting now supplement local employment.
The community keeps a strong Welsh‑speaking identity and a history tied to slate extraction, visible in rows of quarrymen’s cottages and local traditions such as choirs and rugby; the industrial heritage combined with upland scenery makes it a quiet base for walkers and anyone interested in the story of North Wales slate.
