Underground Adventure

Our underground adventure is an amazing experience and is suitable for all ages and abilities! We explore an ancient underground slate mine long since abandoned by the mine workers. We work our way through the massive access tunells and huge underground chambers quarried out by the late slate quarrymen over 200 years ago. Dont worry if you're claustraphobic; this isn't a cave and we won't be crawling anywhere, it's an underground cathedral!

During the underground adventure we follow in the footsteps of the slate quarrymen. After a scenic walk up the valley we enter the old mine workings. We show you how they quarried the rock and the difficult conditions they worked in, deep underground. This is real industrial archeology and it's an exciting and unusual adventure experience. We'll also find some of the artefacts left behind such as abandoned tools and machinery.

As we explore the mine we climb up the levels crossing 6 floors. climbing the mountain underground. We ascend the maze of chambers until we emerge in to the light near the summit, some 400ft higher up the mountian. The slate mines offer a unique and exciting environment to explore, cone and find out what it's all about!
