A dramatic landscape of orange and purple rocks, much-loved by science-fiction film-makers. The mountain has been mined for copper and other minerals since Roman times. Some consider it derelict land, others a giant earth sculpture! Public footpaths cross the site and there is on-site interpretation/information by the Amlwch Industrial heritage Trust. The sulphides in the rocks produce very acid conditions, (and very acid waters in the Afon Goch "red river" - actually two rivers which flow north to Amlwch and south to Traeth Dulas). Rinsing equipment and footwear in freshwater afterwards is recommended!
