Treak Cliff Cavern in an underground wonderland of stalactites, stalagmites, rocks, minerals and fossils. Home to Blue John Stone, a rare form of Fluorite with beautiful colours. Popular as an ornamental stone and mined for 300 years. The Clue John Stone in Treak Cliff Cavern can be seen all year around the walls and roof of the Witch's cave.
The guided tour takes you deeper underground to see multi-coloured flowstone adorning the walls of Aladdin's Cave, and further on you can experience the wonder of the stalactites and stalagmites in Fairyland and the Dream Cave. The most famous formation is "The Stork" standing on one leg.
We are famous throughout the world for our unique and large deposits of Blue John stone and some of the most beautiful cave formations found in the UK.
