About Llanfair Slate Caverns

The entry to Llanfair Slate Caverns, this old but significant and famous slate mine, is through the majestic main tunnel, under the spooky twin arches of the crypt, and into the lofty cathedral cavern! High adventure, only really low down!

Remember that the tunnels and caverns you are about to see are all man made over a 100 years ago with only a candle for lighting so best for competently mobile kids not too shy about the dark!

Descend Jacobs ladder and wonder through the tunnels and chambers, and look for the old drilling holes, and the likeness of a human face in the mighty no 6 cavern. It might be stating the obvious but if your children aren't keen o the dark, or being enclosed, this probably isn't a good idea. 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.
