Llechwedd Slate Caverns

Get ready for life in the mine – Victorian style.


Travel 500ft deep into the mine and far back in time on the steepest cable railway in Britain. Join Hywel, his 12 year old son Meirion and brother-in-law Gethin as they battle to survive the terrible conditions underground. Hear from our amazing guides about the brave men who created some of the world’s biggest underground slate caverns, some the size of a cathedral.
