The slate caverns of Llanfair in North Wales were mined between 1890 and 1910. These vast manmade caves have been reopened as a tourist attraction where visitors can experience the extraordinary achievement of the Welsh miners who excavated millions of tonnes of slate using only hand held tools and candle lanterns. Located 1.5 miles south of Harlech, the mines feature nine main chambers each of which has a different theme. There is not much to see on the surface except for a small car park , a cafe, a shop and some toilet facilities. However, once you enter via ‘Jacobs Ladder’ and are free to wander the cool, dark and atmospheric caverns you can really get a sense of the scale and conditions in which the miners had to work. The Slate itself is some of the oldest in the world and is sandwiched between layers of Pre-Cambrian rock. It is not as large as many other slate caverns in Wales but there is greater freedom to explore by yourself. Sections of the popular 1995 film ‘First Knight’ starring Sean Connery and Richard Gere were film at the Lanfair Slate Caverns.
Please note that the caverns can be cold, dark and wet from dripping ground water. It is suggested that visitors wear warm clothing and take additional flashlights / torches. Helmets are provided by the management of the caves.
