Speedwell Cavern is certainly the Peak District’s most distinctive caving experience on offer, mainly due to the fact it can only be accessed by boat. Located at the base of Castleton’s Winnats Pass hill, visitors are first required to descend 105 steps in order to reach the cave entrance, and the mind-blowing underground canal dock found within. Once boarded, the boat makes a gradual descent of over 200 metres, as it gently drifts through the complicated, now sunken, 18th century lead mining tunnels, before reaching the Bottomless Pit lake at the bottom – a cavern so big that it’s often compared to a cathedral!

An expert tour guide is present for the duration of the voyage, who will meticulously explain the lead mining history of the cavern, as you descend deeper, and deeper into the limestone hill.


Speedwell Cavern first witnessed lead mining activity in 1771, following a 14,000-pound investment from Staffordshire businessmen. The cavern already boasted an intricate underground canal system, which was utilised during construction of the mine as a carrier of spoil and ore.

The name Speedwell was given by the miners, who noticed that the water level of the canals never increased, no matter how much spoil and ore they dumped into it. The cavern’s apparent bottomless nature lead many to believe it was actually a tunnel to hell.

Unfortunately for the investors, the mines proved to be unfruitful and were eventually abandoned in 1790. Thankfully, even as early as the late 18th century, Speedwell Cavern’s profitability as a show cave became evident, as hundreds of people flocked to the site to enjoy the pleasures of its unique canal system. Queen Victoria, who was known to frequent its neighbouring show cave Peak Cavern, was recorded as being an early visitor, and even partook in the cavern’s water-based transportation.

In the early days of Speedwell’s life as a show cave, guides were forced propel the boat along using their hands, and later were noted to have ‘legged’ the boat along, meaning that they lay on their backs and kicked the boat along. The boat is now, thankfully, electric powered.

Things to do at Speedwell Cavern

The Boat Journey – Learn the full story of the failed mining endeavours that took place in Speedwell Cave, while, aptly, passing through the old mining veins in a boat.  Visitors are free to alight the boat at the end of the adit and explore the dry-land show caves and caverns, while marvelling at the stalagmites and fluorspar veins. The eerie 490-foot deep lake, known as the Bottomless Pit, is found at deepest part of the tunnel and will surely fascinate all.

Speedwell Cavern Gift Shop – The onsite giftshop offers a wide selection of unique mementos and souvenirs, many of which involve the Peak District exclusive Blue John gemstone.
