Llechwedd Slate Caverns is a visitor attraction in Blaenau Ffestiniog, Gwynedd, Wales. It details of the history of slate quarrying in the town and specifically the Llechwedd quarry in which it is located. It has an interpretive centre which shows how slate was extracted and processed, a reconstructed village which shows how miners lived, and two railways allow visitors to travel into abandoned sections of the quarry.


The 2 ft (610 mm) narrow gauge Miners' Tramway, opened in 1972 under the name "Quarry Tours",[1] is a railway travelling 800 metres underground. The trains are hauled by battery-electric locomotives and travel through tunnels and into a series of quarry chambers. The Deep Mine, opened in 1979, is accessed by the 3 ft (914 mm) narrow gauge[2] Deep Mine Railway, a steep passenger funicular with a gradient of 1:1.8 or 30°. At the foot of the funicular, visitors can walk through the tunnels and chambers. The Deep Mine Railway is the steepest passenger railway in the UK.[citation needed]

In 1992 the Deep Mine displays were upgraded using audio visual technology supplied by Eurodisney[1]

In 2014 the Bounce Below attraction, described as "the world's largest underground trampoline", opened in the mine caverns.[3]


Llechwedd Slate Caverns have been listed as one of the top ten places to visit by North Wales Tourism, the tourism board for this area. It is also claimed to be "winner of every major tourism award".[4]
