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. Check out the Great Orme Mines website for visitor info.

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.

The Winding House, Caerphilly

Housed in a striking glass-walled building on the site of the former Elliot Colliery, the Winding House details the industrial history of the Rhymney Valley.

This incredible piece of engineering is kept in working order by a team of devoted volunteers and you can even see it in action on the final Saturday of each month. As well as the engine, the Winding House is home to a collection of documents, photographs and objects which illustrate day to day life here in South Wales at the height of the Industrial Revolution.
