An Adventure into the past...
Situated in the heart of Snowdonia we have been quarrying for slate here since 1836 and take visitors deep underground into the mine. This year sees the launch of the Victorian Mine Tour - local Guides take you through huge Caverns to experience the life of a Victorian family at work.
Take the train underground...
Take the steepest cable railway in Britain to explore the old mine workings!
