Treak Cliff cavern

Your guide will explain how miners in the 1750’s constructed a tunnel using only hand tools to reach the Blue John stone deposits in the hill. Treak Cliff Hill is the only place in the world where Blue John stone naturally occurs an d it is believed that the name Blue John comes from the French words Bleu et Jaune (Blue and yellow).

On your tour you will see veins of Blue John stone across the cave roof, and the “Pillar” the largest piece ever found.

It is very impressive; your guide will point out fossils in the limestone rock which formed the hillside above you 330 million years ago.

Your guided tour descends deep into the hill where you will experience the wonder of underground limestone cave formations; multi-coloured flowstone adorns the walls of the Aladdin’s cave. Stalactites and stalagmites decorate Fairyland and the Dream Cave. The most famous formation is ‘The Stork’, standing on one leg’.

The Cavern is of international fame and geological importance.

It has been a designated site of specific interest for many years and by agreement with English nature all the Blue John Stone deposits on the visitor route are preserved.

However Blue John Stone is regularly mined in Treak Cliff cavern, from areas not seen by visitors. This is then crafted into fine jewellery, small bowls, ornaments and other decorative items.
