"I really enjoyed my visit to the Blue John Cavern.
It was wet and cold underground, but that just added to the atmosphere.
The caverns itself is very impressive, with lots to see and plenty of history behind it. It’s a really educational experience, learning about the Blue John stone and how the caves were formed.
The tour was around an hour, with a good balance of information and time to look around. Our guide was excellent – knowledgeable, friendly, and made the visit fun and engaging. There are quite a few steps, so it can be a bit of a climb, but it’s worth the effort for what you see inside.
Overall, a fascinating place to visit. Great for anyone interested in geology, history, or just looking for something different in the Peak District.
Highly recommend"

"I had a fantastic experience visiting Blue John Cavern. Our guide, Nigel, was absolutely brilliant – so knowledgeable, full of fascinating facts, and with a great sense of humour that made the whole tour really enjoyable. He is a great guide. The journey down into the deepest show cave was exciting in itself, and while it may not be the most traditionally beautiful cave, it was certainly impressive and atmospheric. Seeing the natural veins of Blue John stone in the rocks was a real highlight and gave the place a unique charm you don’t find elsewhere. Overall, a memorable visit made even better thanks to Nigel’s engaging and funny storytelling."

"We visited Blue John Cavern this Sunday, weather was a little damp which I think may have helped with parking as there didn’t seem to be an actual carpark as such just some bays on the road towards the entrance. I can imagine in good weather it would be much busier.
We were a group of 8 and managed to book tickets when we arrived for a tour with some other people that started around 15 minutes later so there wasn’t much hanging around which was good as the facilities were not extensive.
As someone who is not great with heights and enclosed spaces I was nervous especially when we first walked into the entrance and started the decent of the 245 steps within the cavern in quite a narrow space. Secure hand rails each side on this part helped me keep my balance and get my nerves under control. Once we reached the first open space I was more accustomed to the environment and while the steps are steep in places and a little slippery, the pace was good with plenty of stops and safety was a priority.
Massive thanks to our guide Nigel, whose personality & enthusiasm for the caves along with his knowledge of its history & geology made the whole experience come alive. His help with a torch (or two) was also much appreciated in helping capture some fabulous photos of areas not lit up by the general lighting.
Thoroughly enjoyed this trip, even the climb back up to the top! The surrounding countryside is absolutely stunning and with the cavern being roughly at the base of Mam Tor it was so interesting to see the beautiful countryside but also the hidden beauty beneath the surface."
