Explore a disused Welsh slate mine with Corris Mine Explorers

Welcome to Corris Mine Explorers!

Explore an abandoned Welsh Slate Mine with one of Wales' most experienced Mine Explorers.

This rare opportunity takes you into the old Braich Goch slate mine, in Mid Wales, which was first worked in 1836 and abandoned by the miners around 40 years ago. More than 130 years of history is captured inside waiting to be discovered. It is as if the mine has just closed. Machinery, tools, even the candles and discarded cigarette packets are still in place as the miners left them.

Corris Mine Explorers Gift Vouchers now available for all of our trips - the perfect gift idea!

Corris Mine Explorers gives you the opportunity to visit these abandoned slate mine workings, to step into the tough working lives of the miners and of past generations. There are 3 trips to choose from; a Taster Trip, a 2 hour Mine Explorer Trip and a Half Day Mine Expedition (4 hours).

This is a part of our heritage and a truly authentic Welsh experience. Definitely not to be missed.


Everyone exploring with us at the moment will get the opportunity to see two amazingly huge installations - the results of a project named "Man Made Mountains" - watch the video, our posters are the first two shown on the film.

"...to hear some of the stories of life in the mine brought it all to life in the most exhilarating way."Mike Parker, co-author, Rough Guide to Wales, click here to read Mike's full article.

"Heard about the tour by chance. So glad we grasped the opportunity. Undoubted highlight of our week's holiday in Snowdonia" Eddie E. explored 2016.
