Llechwedd Slate Caverns
Enjoy breathtaking views of Snowdonia before descending into below-ground caves, lakes, and hand-carved tunnels on the UK’s steepest cable railway at the Victorian-era Llechwedd Slate Caverns. This family-friendly museum and activity center in the heart of Snowdonia National Park offers visitors an immersive introduction to Welsh mining history via interactive experiences, demonstrations, and more.
Learn about the history of slate—produced in the area since 1836—at Llechwedd Slate Caverns, which combines several attractions in one. Wander the mock Victorian village, have fun at one of the world’s only subterranean playgrounds, watch slate-splitting demonstrations, and take part in hands-on workshops. Adventurous travelers can also mountain bike and zipline at one of Europe’s longest zip courses.
While there’s plenty to explore independently, there are also daily guided tours of the Victorian mine, as well as adventure excursions which span the entire 2000-acre (800-hectare) site. During the latter, ride in an ex-military truck and sip hot chocolate, before descending into the mines.

Mining in Wales
Mining has historically played a crucial role in the Welsh economy, particularly the coal mines of the Rhondda Valley and wider South Wales. However, slate mines tended to dominate in North Wales and at Llechwedd Slate Caverns visitors can get an insight into the region’s slate mining history, process, and industry. In fact, Snowdonia's slate landscapes are even UNESCO-recognized.
