Parys Mountain Heritage Trail

Parys Mountain on Anglesey's north coast is one of the most visually striking landscapes in Wales, a former copper mine that was the largest in the world during the 18th century. This 3.5km circuit follows the heritage trail through a terrain of vivid ochre, rust-red and purple spoil heaps, shallow toxic pools of brilliant turquoise, and exposed rock faces that look more like a Martian landscape than a Welsh hillside. The mining ceased in the 19th century but the mineral contamination has prevented vegetation from reclaiming the workings, preserving an eerie, otherworldly moonscape. At just 100 metres of climbing on gravel paths, the walking is easy but the visual impact is extraordinary.

Off-lead potential on this dog friendly walk is limited as the mining heritage means some areas have unstable ground and the coloured pools contain dissolved copper and other minerals that are harmful if ingested. Dogs should be kept on leads and away from standing water throughout. The open moorland beyond the mine workings carries good heather scent and the elevated position gives views across to Snowdonia and the Irish Sea. The gravel paths are firm and well-drained. Parking is available at the small car park on the mountain road. Amlwch, the nearest town, has the Dinorben Arms which welcomes dogs. A short but unforgettable walk that shows a completely different side of Anglesey.
