3. Half Day Mine Expedition

Mon 1 Jan 2018 to Mon 31 Dec 2018

Delve around the secret underground world of a Welsh slate mine, with one of Wales' top Mine Explorers; abandoned and forgotten yet full of relics,stories & adventure. Kitted up you'll experience & explore 10+ rarely visited chambers.

Our Half Day Mine Expedition takes you into parts of the mine, hand-dug and worked by Victorian miners in 1836 and areas worked up until the 1970s when the mine was abandoned including rarely visited chambers. As the door creaked shut for the very last time a virtual time capsule was left behind which you can now explore. After years of research, our top Mine Guide will share stories of mining life as you explore the underground with some climbing and scrambling if you wish (these parts of the trip are optional). We always explore in small groups and can largely tailor make each trip to meet the wishes, interests and abilities of each group member. You'll discover old mining tools, machinery, drinking vessels, candles and cigarette packs discarded by the miners whilst stories of life in the mine spill out in such a way you can almost feel it creaking back to life. The Half Day Mine Expedition is exhilarating enjoyment - 100% authentic, historic, adventurous and fun.

Kit provided: Helmet, cap lamp, lamp belt & safety clips. Walking distance: 2 miles plus.

Please allow extra time for your journey due to forestry work taking place nearby. Please ignore the diversion signs as the A487 road between Machynlleth and Dolgellau is open. It will close Intermittently for 10 minute intervals just south of Corris and then reopen allowing traffic to pass.

The T&Cs below include really important information about your trip including what to wear and to bring with you etc. Please read them carefully before accepting them. If you're booking for 6 or more please phone us on 01654 761244 to book your trip.
