“⭐⭐⭐⭐⭐ A fascinating and genuinely memorable underground experience in the slate mines of Snowdonia. The scale of the mine is difficult to appreciate until you are actually inside, surrounded by enormous chambers, narrow passages, steep ladders and underground pools. It feels like stepping into a hidden part of Welsh history that has been left almost untouched. One of the most impressive aspects is seeing the remains of the original mining operation, including old rails, carts, metal supports, chains and equipment still inside the tunnels. The dates and markings carved into the slate make the experience feel very real and give you an appreciation of the extremely difficult and dangerous conditions in which the miners once worked. The flooded chambers are especially atmospheric. The deep green water, huge slate ceilings and inflatable raft create an almost otherworldly setting. Every section of the mine offers something different, from dramatic rock formations and abandoned machinery to openings where the greenery and daylight contrast beautifully with the darkness underground. This is much more adventurous than a conventional visitor attraction, so sensible clothing and sturdy footwear are essential. The ground can be wet, uneven and slippery, and some areas may involve climbing, ladders or confined spaces. It may not suit anyone who is uncomfortable with heights, darkness or enclosed environments, but for people who enjoy history, exploration and unusual adventures, it is an incredible experience. The surrounding landscape is also beautiful and makes the journey worthwhile in its own right. I would recommend booking with an experienced guide rather than attempting to explore independently, as these are historic mine workings with water, drops and unstable areas. An unforgettable way to discover the industrial heritage of North Wales and one of the most unusual experiences available in Snowdonia. Highly recommended for adventurous visitors, photographers and anyone interested in mining history.”

“We had an awesome time doing the 5-hour experience today, and Andy was a fantastic guide! I can be a bit nervous about new fitness-related experiences because of a previous significant injury to my right leg. I’ve recovered well, but it’s not as strong as it once was, so I wasn’t feeling particularly confident going into this. I managed really well though! I was a bit slower and more wobbly in some areas than the others 😅, but I was never made to feel self-conscious about it, which I really appreciated. The challenges were so much fun, definitely an experience you will remember forever! We were also lucky to be with a lovely group of friendly Americans, and we really enjoyed chatting with Andy throughout the experience. Learning about the history of the mines and the surrounding area was a great added bonus too. A couple of practical tips for anyone doing it: we took the instructions about bringing food and drink a bit too literally and packed a LOT 😂. There wasn’t really a stop for lunch (which was absolutely fine as the other group hadn’t brought any food/drink with them!), and you probably only need a bottle or two of water and perhaps a small snack. I also hate being cold, so I layered up rather enthusiastically 🤣. In hindsight, I’d recommend: • Thin leggings with lightweight waterproof trousers over the top (or quick-dry/technical trousers, like my partner wore) • A long-sleeved top and thin, breathable waterproof jacket (my partner wore a quick-dry sports T-shirt with a moisture-wicking jacket). We both took our jackets off during the experience but I was glad to have mine. Overall, we had such a brilliant experience and would absolutely recommend it! 🥰”

“Did the Ultimate Xtreme. Our guides were Chris and Dave two really nice guys, chilled. They explained every challenge we faced making the experience very nice. 7 hours underground sounds long but time flies easy, you beeing concentrated on the climbings, balancing on edges, enjoying the ziplines and the stories behind the mine, life in and around the mine, how miners worked. No one is rushed or any pressure. You need a good physical condition for the climbings and flexibility really helps. Once you receive your confirnation e-mail just follow the instructions and check the meeting point, depending on your activity they start at different places. If you think about overcoming fears don't even hesitate...go...you won't regret it. I would recomnend a small back pack with front strap at your chest and stomach. After the cave adventure you can enjoy the Sun and warm summer day at the lake or do hiking.”
