Slate Mountain Adventure

Discover the whole story of The Slate Caverns with the Slate Mountain Adventure.

Starting with an adrenaline fuelled journey to the furthest reaches of the site on a ex-military truck, you’ll travel into the rich history of the 2,000 acre quarry, visiting the likes of Maenofferen, Diffwys, Foty and Bowydd Mines - an area famed for it's thrilling, and sometimes tragic, history. Some of the areas are over 300 years old!

If the weather is in your favour, keep an eye out for Harlech Castle, Trawsfynydd nuclear power station and the Snowdon horseshoe - all of which are visible 1,500 foot pinnacle of the tour!

Once you’ve finished your pit stop at the Cafe, it’s time to catch a train! Descending 500 feet into the Llechwedd Deep Mine (the deepest accessible area of the site), your guide will lead you through ten massive subterranean chambers, culminating in an beautifully emotional tribute to the mine workers, further highlighting the incredible stories of the miner and the difficult working environment they had to endure.  PLEASE NOTE THAT IT IS ESSENTIAL TO BE ON SITE 30 MINUTES BEFORE COMMENCEMENT OF THE TOUR FOR YOUR SAFETY BRIEFING.
