Well, nestled deep underground, near the village of Castleton in the Hope Valley in Derbyshire lies one of England’s most awe-inspiring natural wonders – the Blue John Cavern.

With stunning geological formations, spacious caverns and not too tricky sets of stairs, the Blue John Caverns makes for an unforgettable family day out from Manchester and the surrounding area. Read on as we give you the complete lowdown on visiting these magnificent caverns with kids!

A Short History of the Blue John Caverns

Nestled in the beautiful Hope Valley not too far from Disley and Lyme Park, Blue John was first discovered by the Romans around 2,000 years ago, Blue John is not only Britain’s rarest mineral, but also the only location (so far) known for it to exist across the world. In recent years, it has allegedly been found in excavations in Pompeii.

Excavation of this mineral has largely been done by hand with most of the excavation happening over the last 500yrs. According to our tour guide – George, it was with the assistance of some French miners who came over during this period that the name ‘Blue John’ came into existence.

The colour of the precious stone can have a blue – yellow tint to it. In French, this translates to ‘blue-jaune’. The local Derbyshire miners had no idea what this translated to, but kept hearing ‘blue jaune’. They came to like the name and decided to call it Blue John.

Taking in the Scale and Layout of Blue John Caverns

The standard walking tour through Blue John Caverns covers just a small section of the vast cave network. You can only visit the caves as part of a guided tour. You can’t book these online so arrive and then you may potentially have a 15 – 30 minute wait for the next tour. However, there is a little cafe selling basic refreshments and a shop selling some Blue John jewellery to keep you occupied.

The tour starts from the entrance tunnel fitted with lighting and safety rails. After a short descent (90 steps), you emerge into the grand first cavern with towering columns and fascinating banded Blue John seams in the walls. Kids will love spotting shapes and objects in the rocky walls and high ceiling here!

Fun Fact: The farthest point of the standard Blue John Caverns tour lies around 150 metres underground.

Beyond the Pillars lies the aptly named Giant’s Cavern with walls rising up to 12 metres. See if you can spot the distinctive Great Pyramid structure as you walk through this massive space.

The caverns save some of their most mesmerising formations for the end of the tour.

Kids will be thrilled to count over 295 steps in and out on the walking route through the caves. These are in sets of steps of around 50 – 90 steps at a time.

Practical tip:

Sam was probably the youngest on the tour. He’s very headstrong so would never allow me to carry him. However, at the same time, there were definitely parts that I would not feel comfortable carrying him, due to the steps being wet and deep, with narrow spaces. The first part of the tour was definitely the hardest. There are 90 steps at this part of the tour and they do feel like they take for ages. However, once you get past this section, it’s pretty straightforward. It’s also easier going up than down!

This is one thing to consider when visiting. It would be fine to go with young babies carried in a sling, whilst Mila had no problems at all. But the 2 – 4 ish age range is a difficult age to assess suitability.

We went at the back and went at his pace. But just be mindful of this!

There is no way you could take a pram or stroller!
