Llechwedd Caverns

Llandudno & Rhos on Sea

Buried deep under the mountains of Snowdonia lies an extraordinary story: a rock revolution that shaped the look and feel of the world as we know it.

Llechwedd’s Slate Mountain Adventure guides you on a truly unique experience through the historically significant quarry. Starting with an exhilarating ex-military truck ride to the highest peaks of the 2,000 acre site, you’ll visit the vast quarries of Maenofferen, Diffwys Casson and more and discover how they are a key part of the bid to make the North West Wales Slate Landscape a UNESCO World Heritage Site. Along the way, make sure you have your cameras handy as you’ll take in the breathtaking views of South Snowdonia including Snowdon itself, Moel Siabod, Blaenau Ffestiniog’s own Moelwyn mountain range and the Irish Sea beyond.
