The Blue John Stone Experience

Peak District National Park

The experience

An underground adventure to discover Blue John Stone, a rare, semi-precious mineral found at only one location in the world – in the caves of Castleton, Derbyshire in the Peak District. Work with Treak Cliff Cavern family and staff to get really hands-on with this unique stone. Discover its history before producing three items to take away; an item of silver jewellery, a window hanger/ decoration, and a polished slice or chunk (which can be found by searching in the mines).
