Underground mine exploration in North and Mid Wales
Slate mining and quarrying was a huge industry in North and Mid Wales, and the effects on our landscape can still be seen today. There are plenty of mining attractions for people who love a bit of industrial archaeology to visit safely, either for fascinating history tours or for an exhilarating explore underground.
Find out more about the UNESCO Slate Landscape of Northwest Wales.
Great Orme Mines, Llandudno
Craggy, echoey and about as atmospheric as they come, the Great Orme Mines site was uncovered in 1987 and features a Bronze Age Cavern dug by miners with stone and tool bones 3,500 years ago. Don a hard hat and witness the latest discoveries in one of the world’s largest prehistoric mines.
Zip World Llechwedd, Blaenau Ffestiniog
Blaenau Ffestiniog was once home to several huge slate quarries. The effect of the industry is still clear to see, with huge slate waste tips forming a unique landscape. The town is now a thriving hub for outdoor enthusiasts well as industrial archaeology fans.
History and adventure combine to brilliant effect at Zip World Llechwedd with the Deep Mine Tour. This tour is a family friendly interactive experience with new technology; the first to use augmented reality in an underground setting with iPads providing a window on the past. You access the caverns using Britain’s steepest cable railway to levels of 500ft underground. Find out how the slate was mined and hear the stories of the people who worked there.
Then there’s ‘Caverns’, an exhilarating 3-hour course of underground zip lines, rope bridges and tightropes - a perfect option for adventurous families and a fantastic reimagining of the hidden crevices and winding passageways found beneath the surface of the earth. Bounce Below is home to no less than six huge trampoline-style nets stretched out across a subterranean cavern said to be twice the size of St Paul’s Cathedral. If that weren’t enough, the highest trampoline hangs a mighty 180ft above the cave floor! Or try the Underground Golf, following a course through the caverns which, as well as being immense fun, integrates the history of the mine.


Go Below, Eryri
For those keen on pushing themselves even further, the team at Go Below Underground Adventures let you pick between three nerve-jangling packages. The 7-hour ‘Ultimate Extreme’ package includes not only the longest and steepest underground zip line in the world (aptly nicknamed ‘Goliath’) but also the world’s first - and only - 70ft underground free fall. Each trip offers hours of mine exploration combined with zip lines, cave climbing, traversing and abseiling, all underground!

Sygun Copper Mine, Beddgelert
More than a century after being abandoned in 1903, Sygun tells the story of Victorian copper miners in colourful fashion. This is the place to trace copper ore veins, silver and gold within the confines of illuminated caves, then relax within its beautiful natural surroundings in the hills of Eryri (Snowdonia).


Llanfair Slate Caverns, Harlech
Explore the nine caverns at Llanfair Slate Caverns, a virtually untouched slate mine. Find out what the conditions were like for the workers. The tour is self-led - perfect for taking your time to absorb the atmosphere. You are provided with a hard hat and a torch and dogs are welcome to go along as well.
Corris Mine Explorers, Corris
Follow in the footsteps of Victorian slate miners at Corris Mine Explorers with one of the expert guides. You'll experience the broad tunnels and cavernous chambers where the world's finest slate was excavated by both hand and explosive before being shipped around the world. Braich Goch slate mine was first worked in 1836 and finally abandoned by the miners in the 1970s. From the moment you step through a hidden door in the mountainside, you'll be immersed into a way of life and work which changed little throughout the mine's history.
King Arthur's Labyrinth, Corris
For a more sedate, family-friendly experience, step aboard a boat and wind through a labyrinth of tunnels and caverns in historic southern Eryri (Snowdonia), at King Arthur's Labyrinth, Corris. Based in another part of the Braich Goch mines, this time your guide is a hooded boatman on this voyage with a difference, with a litany of Dark Age tales told against the backdrop of luminous expanses of water.


Underground mining experiences in South and West Wales
Down in South and West Wales, the deep coal mines produced millions of tons of black gold to fuel our industries. While the mines are no longer operational, you can still visit several, now open as brilliant museums.
A Welsh Coal Mining Experience at Rhondda Heritage Park Museum, Trehafod
A Welsh Coal Mining Experience at Rhondda Heritage Park Museum stands on the site of the former Lewis Merthyr Colliery, which was once one of more than 50 collieries in the surrounding valleys, only closing during the 1980s.

Big Pit National Coal Museum, Blaenavon
Another great mining attraction not to be missed is Big Pit, our National Coal Museum. Located in the World Heritage Site of Blaenavon, this former working mine opened as a museum in 1980. Led by former miners you can discover what the mine was like as you descend 100 metres underground into it’s dark depths. Entry is free.
