Group Visits

The National Slate Museum welcomes group visits and aims to provide an enjoyable and rewarding experience.



Year round demonstrations and talks particularly suited to families include slate splitting demonstrations by our friendly quarrymen and talks about UNA the quarry engine — where you can see how an engine actually works.
