Castleton’s Treak Cliff Cavern has a unique history. Originally a working mine 300 years ago, it’s now a major visitor attraction in the Hope Valley area of Derbyshire. It’s also still a working mine – Castleton is the only place in the world where the beautiful Blue John stone can be found.

The new Treak Cliff Cavern Interpretation Centre is part-funded by the European Agricultural Fund for Rural Development - to upgrade the visitor offer, by providing new toilets, heritage and interpretation centre. Project reference number: 101006.
