We are delighted to announce that Corris Mine Explorers has reopened, safely. We are offering the same fantastic award winning underground explorations with additional measures in place for your safety.

Located in the foothills of Southern Snowdonia in Mid Wales, our underground trips take you into parts of the old Braich Goch slate mine, hand-dug and worked by Victorian miners in 1836 and areas worked up until the 1970s when the mine was abandoned. 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 Guides 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). All of our trips run with a small group of explorers which means that we can largely tailor make them to suit your wishes, interests and abilities and those of the other members of your group.

You'll discover old mining tools, machinery, drinking vessels, candles and cigarette packets 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. 100% authentic, adventurous and fun.

During the trips you're taken into the dark, damp tunnels and underground workings, in small exclusive groups by the experienced guides. There are 2 trips to choose from; the 1 hour Mini Mine Explorer which is great for families (minimum age 8) and anyone wishing to try it out first and the 2 hour Maxi Mine Explorer Trip where you get to explore deeper into the old mine with optional use of ropes and ladder. You'll be thrilled as stories from the historic mine spill out.

For pre-booked groups of 6 people or more we also offer a 4 hour Exclusive Mine Expedition where you'll take on an exhilarating new route and venture into fresh territory. We also offer Underground Sleepovers (yes really!) for pre-booked groups of 6 explorers or more.
