Treak Cliff Cavern

​Treak Cliff Cavern is a genuine wonder in the heart of the Peak District. Treak Cliff Hill is the only place in the world where Blue John Stone naturally occurs. The mineral Blue John Stone is a unique banded form of Fluorspar. It is believed it was originally given its name from the French “bleu et jaune” – the “blue and yellow” stone. It was mined in the eighteenth century with the Derbyshire folk coining the name. Treak Cliff Cavern continues to mine, process and manufacture ornamental items and jewellery from Blue John Stone today. We also have some of the finest stalactites in the Peak District. Dogs are welcome at Treak Cliff Cavern at all times. Telephone 01433 621487
