Parys Mountain (Mynydd Parys)
Walk the waymarked heritage trail through the coloured, rocky landscape of a former copper mine near Amlwch, worked since the Bronze Age.
Just south of Amlwch, Parys Mountain is a striking landscape of bare rock in shades of red, orange, yellow and purple, left by centuries of copper mining. Copper was dug here in the Bronze Age, and after a large deposit was found in 1768 the mine grew to dominate the world copper market for a time, giving the area the name Copper Kingdom.
A signed heritage trail, created by the Amlwch Industrial Heritage Trust, leads around the old workings, including a level walk around the top of the Great Opencast with a viewing area over its colours. You may see birds such as skylark, meadow pipit and chough.
Good to know
Stick to the marked paths: there are steep drops, deep shafts and uneven, rocky ground. The Copper Kingdom museum at Amlwch Port closed in late 2022 and is not open to visitors. The Trust plans a new visitor and learning centre on the mountain itself and was looking for architects in October 2025, but no opening date has been announced.
