What we offer

We are the first to use augmented reality in an underground setting with iPads providing a window on the past.

Visitors access the caverns using Britain’s steepest cable railway to levels of 500ft underground and the passionate tour guides – many of whom have local connections with the mine and whose families can be traced back to Blaenau’s past – creates great memories for our visitors.

What makes us a great choice?

Llechwedd Deep Mine is a place children use miner’s primitive drills and hang by chains from the chamber walls just as the men would have done over 150 years ago. They lay fuses setting off powerful blasts using a Victorian plunger - which is proving to be very popular! Visitors gasp at the real life dangermen as they bring to life one of the most death defying elements of Victorian health and safety!

You’ll learn more about how this amazing landscape was formed, and why it is now the subject of a UNESCO World Heritage Status bid. You’ll take in views of North Wales like no other and have the opportunity to snap some great photographs.
