Llechwedd Slate Caverns
Ceudyllau Llechwedd
A Victorian slate mine in Blaenau Ffestiniog. Ride the UK's steepest underground cable car into the mine, with an underground trampoline and zip lines also on offer.
Ceudyllau Llechwedd opened its slate mine in 1846. The Deep Mine tour rides the UK's steepest underground cable car down about 150 metres, where guides and multimedia projections bring the lives of Victorian miners to life. The site is now run by Zip World and offers attractions including the Bounce Below underground trampoline, the Caverns zip line inside the mine, and the Titan zip line above ground. Blaenau Ffestiniog, where it sits, is surrounded by slate mountains and is part of the World Heritage Site “North West Wales Slate Landscape.” Visits must be booked in advance. The town is the terminus of the Ffestiniog Railway.
