The Blue John Stone Experience at Treak Cliff Cavern
Blue John Stone is a rare, semiprecious mineral found at only one location in the world – in the caves of Castleton, Derbyshire in the Peak District National Park.
This is a truly unique, “hands-on” experience enables you to work with Treak Cliff Cavern family and staff to get really hands-on with this unique stone.
Learn about the geological formation of caves within the Peak District National Park and meet the family who own and care for the mine.
Go prospecting for your own piece of Blue John stone in the mines here at Treak Cliff Cavern. Our expert craftspeople will guide you through polishing your selection and you’ll also be able to choose additional pieces from the workshop to make into a window hanger and a piece of silver-mounted jewellery.
Places are strictly limited – for booking information please see below.

What do I need to bring?
The underground temperature is a constant 10°C (50°F) so we advise that you wear suitable clothing.
The cavern floor is constantly wet due to the natural underground environment; therefore suitable footwear must be worn within the underground area. Please be aware that the most ‘sensible’ footwear can cause an individual to slip.
A selection of hot and cold food and drinks are now available from our new ‘Café on the Cliff’, or you are welcome to bring your own packed lunch.
