The Corris Mine Explorers is located at the Corris Craft Centre, adjacent to King Arthur's Labyrinth. Nevertheless, it seems they are operated by different operators and the style of the tours is quite different. While King Arthur's Labyrinth offers multimedia experiences for average tourists, the mine explorers do mine trips which are a bit more physical. Undeveloped parts of the historic Braich Goch Slate Mine with only minimal security infrastructure are visited in small groups on cave trekking tours. Visiotrs are equipped with rubber boots and helmets with headlamp. Or if you have appropriate caving gear you can bring your own. Do not forget spare clothes to change after the trip, and probably a towel. It seems the Corris Mine Explorers has no ticket office or other surface buildings. Participants book online and meet at the Tourist Information Point at Corris Craft Centre. So be aware that there is no infrastructure to change clothes or take a shower afterwards.
