About Us

Llechwedd Deep Mine Tour is a family friendly interactive tour with new technology, amazing effects and features a beautiful projection over the undergroud lake. It is a place children use miner's primitive drills and hang by chains from the chamber walls just as men would have done over 150 years agao. They lay fuses setting off powerful blasts using Victorian plunger - which is prving 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.

Customers access the cavern using Britain's steepest cable railway to levels of 500ft underground and the passionate tour guides - many of whom hvae local connections with the mine and whose families can be traced back to Blaenau's past - create great memories for our visitors.

Our Quarry Explorer is an off road adventure that will take you right into the heart of Llechwedd's man made mountains. Travelling in a military 4 x 4 truck you will drive up high to the top of the quarry and into some of the massive craters that were made by blasting the tops off our hundred year old caverns.

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