Blue John and Treak Cliff Caverns.
Blue John Cavern, just outside Castleton, is home to eight of the fourteen known varieties of the stunning Blue-John Stone. Traditional methods in mining are still used here. The cavern is steeped in a history which you can share by taking a guided tour. Then perhaps a visit to the Craft Shop in Castleton to purchase a special souvenier.
Treak Cliff Cavern has been designated a Site of Special Scientific Interest and the deposits on the visitor route are now preserved. There is still mining in the areas not used by visitors and fine jewellery, bowls and ornaments are on sale in the Castleton Gift Shop. Guided tours are run throughout the year and Carols by Candlelight are very popular..booking essential!
