There are several wonderful caves and caverns around the Peak District National Park and I had the chance to visit one of them a few years ago, the Devil’s arse. This time, we visited another interesting cave, the Treak Cliffs Caverns.
The cave is also located close to Castleton and is well-known for the ornamental mineral, the Blue John, that is still currently excavated. The Blue John can also be found in another cave nearby, the Blue John Cavern. They extract the stone in small quantities, just enough to create beautiful jewellery pieces and ornaments. The Blue John came from the French “Bleu Jaune” (blue-yellow), and is a form a fluorite with stripes of purple/blue and yellowish colours, hence the name.
The cave is made of limestone and there is a lot of stalactites and stalagmites, as well as fossils in the cave, but the star of the show if of course the Blue John! The Pillar is the largest piece ever found and is on display. Our guide explained extensively how the miners dug the tunnel using only their hands to reach the Blue John veins hidden under the hill and it was really fascinating!
I would love to visit the other caves nearby, it seems they are all very different! At the end of the visit, we walked on top of the hill to have a gorgeous view of the valley
