Blue John Cavern, Castleton

Gift & Specialty Shop · Shopping
Head underground with a tour of the Blue John Cavern. The cavern is named after Britain’s most rare mineral, blue john, which is still mined here in small amounts outside the tourist season. Be guided through the caves by one of the miners and learn how the caves were formed. Discover the areas that have produced some of biggest pieces of blue john ever mined. Take in the natural beauty of the forms and colors that the minerals have produced, including stalagmites and stalactites. Visit the craft shop to purchase some of your very own blue john set in jewelry and ornaments. Sensible footwear is a must as the cavern contains lots of steps.

  • Our guide made the experience incredibly interesting! The caverns are surprisingly deep, and you'll enjoy the 247 step descent! Pace yourself going back, as you'll retrace those same steps upwards. It's not a suitable attraction for people with heart and lung conditions (and possibly some other conditions as well), and children who need to be carried (the stairs are steep at points and slippery, so you'll need to be very careful and always hold on to the railing). Dogs are allowed on short leads.
  • Like the other caves in the area this is a stunning place to visit full of natural beauty and wonder. So go even if you are not into spelunking you will not regret it, but please resist the urge to try pick Blue John out of the cave walls. It doesn't work and you will just break your finger nails. What did you expect it's stone. So go make a weekend trip to the area and have a great time in the nature beauty of the caves and peak District
