Treak Cliff Cavern is a genuine wonder in the heart of the Peak District. Treak Cliff Hill is the only place in the world where Blue John Stone occurs naturally. The self-guided audio tour will explain how Blue John Stone was formed, miners in the 1750s constructed a tunnel using only hand tools to reach the Blue John Stone deposits within the hill, and you will see incredible veins of the stone across the cavern roof and hear about the recent discovery of the ‘lost vein’ of Blue John Stone that had been hidden for almost 70 years. Your audio-guide will point out fossils in the limestone rock which formed the hillside above you some 330 million years ago. The tour descends deeper into the hill where you will experience the water worn chambers of natural limestone cavern formations. Multi-coloured flowstone adorns the walls of Aladdin’s Cave. We also have some of the finest stalactites in the Peak District that decorate Fairyland and the Dream Cave. The most famous formation being “The Stork”. The walking tour lasts around 45 minutes and you can stop and take photographs and go at your own pace. As you come out of the Cavern the view of Castleton and the Hope Valley stretches for 10 miles in front of you. Our small museum houses a wealth of historic Blue John Stone treasures collected by the owners, and displayed for everyone to enjoy. Discover more about the formation and history of the Cavern and the family who care for it today. You can browse our shop to choose Blue John jewellery, and items made in our onsite workshops, or choose rocks and minerals from all over the world! 
After discovering the caverns, learn how to polish your very own souvenir piece of Blue John Stone which is included in the ticket price. Working with one of our crafts people, you will select, prepare and polish a slice of Blue John Stone to take home. 

Our Cafe hatch serves hot & cold drinks and snacks.

Children aged 4 and under are not charged for cavern entry and do not need to have tickets for the cavern. But a £6.50 charge is applied if they would like to do the stone polishing activity.  
Be aware we are on a steep hillside so there is no wheelchair access to or inside the Cavern, and some areas underground are low and narrow. At least ONE adult (18+) must be present for insurance policies, so please only book if there is an adult in your party. We have activity sheets for children, for different age groups to help them enjoy the cavern too.
