Llanfair Slate Caverns


Our Caverns 


 Epic Man Made Caverns


The entry to this old and important slate mine is through the main tunnel, under the twin arches of the crypt and into the lofty cathedral cavern. The tunnels and caverns you will see are all man made over 100 years ago with only a candle for lighting. The slate in this mine, found in the veins between layers of Pre-Cambrian rocks, is among the oldest in the world, and many industrial towns of Britain and Ireland have the original roofs of Llanfair slate.

Descend Jacobs ladder and wonder through the tunnels and chambers, and look for the old drilling holes, and likeness of a human face in the mighty No 6 cavern. As you emerge from the caverns, you face the breathtaking view of Cardigan Bay, from the Preseli mountains in the South to the Lleyn Peninsular. Look down at Shell Island and the Artro Estuary, and at low tide trace the fourteen mile long natural causeway of St Patrick
