This is a Self guided audio tour of Treak Cliff Cavern using your own Smartphone, with a Christmas seasonal twist combined with workshop time with our Craftsmen to make a Blue John Christmas decoration. The cavern is decorated with fairy lights, Christmas trees, and candles. Rocks and minerals from around the world are incorporated into the decorations to create even more Festive Feel. The Christmas Rocks Trail focuses on the decorations and the minerals as you take your journey through the Cavern. Underground you see the unique mineral Blue John Stone, found only here in Treak Cliff Hill. On your 50 minute audio tour see ancient fossils, rare minerals and the finest stalactites and stalagmites in the Peak District. In the workshop the crafts people help you select a slice of Blue John Stone from a variety of natural shapes and colours to create your Christmas decoration. Discover even more history of Blue John Stone and artefacts and the family who care for the Cavern in our museum,
