Explore a disused Welsh slate mine with Corris Mine Explorers

Corris Mine Explorers in Mid Wales!

Adventure, History, Discovery and Fun all rolled into a fantastic underground attraction with one of the best Mine Explorers in Britain.

Tucked away in the hillsides of Corris in Mid Wales you will feel the dark, damp mine workings come alive as your expert Guide shares its stories. An authentic Welsh adventure into an unknown dark world. Braich Goch Slate Mine in Mid Wales was hand dug by Victorian miners in 1836 and worked for more than 130 years – discover the virtual time capsule that was left behind as the door creaked shut for the last time in the 1970s…
