Taking a trip underground might not be on everyone’s bucket list, but if you’re anywhere near Cantabria and curious about mining history or natural cave formations, this guided tour of the Udías mines is worth considering. It offers a chance to walk through the tunnels of one of the region’s most significant mining sites — the largest zinc and lead mines in Cantabria — and to explore a stunning natural cave.
What I really appreciate about this experience is how accessible it is. It’s described as very easy to visit, with equipment provided, making it a great option even if you’re not an experienced explorer. Plus, with knowledgeable guides in speleology and geology, you’re in good hands whether you’re a solo traveler, a couple, or a small private group.
A possible downside is that this tour isn’t suitable for everyone: it’s not recommended for children under 6, pregnant women, or folks with mobility issues or claustrophobia. So if you’re looking for a family-friendly adventure or have specific health considerations, you might want to pass on this one. But if you’re up for a safe, informative, and genuinely interesting underground walk, this tour is a solid pick.
All in all, this experience suits those with a curiosity about mining, geology, or natural caves, and who want an authentic glimpse into Cantabria’s industrial past without the hassle of complicated logistics or strenuous activity.

A Closer Look at the Udías Mines Tour
If you’re the type of traveler who enjoys combining history, geology, and a touch of adventure, this tour hits all those marks. It’s not just a quick peek into a mine; it’s a two-hour journey through a piece of Cantabria’s industrial heritage, with the added bonus of seeing a natural cave that’s part of the region’s geological landscape.
The Itinerary and What You’ll Experience
The tour begins in the quiet village of Udías, at a location right in front of the Pumalverde church. From there, you’ll hop into a van for a quick 10-minute drive to the site. This short transport segment is more about convenience than a scenic experience, but it keeps things simple and straightforward.
Once you arrive, you’ll be greeted with a safety briefing and outfitted with all the necessary gear — overalls, helmets, gloves, and boots. This is a thoughtful touch that reassures you about safety and comfort. After gearing up, the real adventure begins.
For the next 1.5 to 2 hours, you’ll follow your guide through the galleries and tunnels of the Udías mines. These tunnels aren’t just a dark labyrinth; they’re packed with visual and geological interest. You’ll see mineral deposits in the gallery walls, such as galena and blende, and observe formations like eccentrics — mineral structures that form in unique shapes and are quite mesmerizing. You’ll also get a sense of what life was like for miners working in these tunnels, and learn about the region’s mining history, which spans from the mid-19th to early 20th century.
The guides are described as extremely attentive and knowledgeable, helping you understand the mining process and explaining the mineral formations. One reviewer even praised Manuel, a guide who was particularly kind and detailed, making the experience not just educational but also personable.
The Natural Cave Access and What Makes It Special
After the mine exploration, you’ll step out into the open air and take a breather. The tour includes access to a natural cave, showcasing formations that are naturally created rather than man-made. This part of the experience is particularly interesting for those who enjoy geology and natural scenery. The cave’s formations, such as eccentrics, provide a visual treat and serve as a reminder of the region’s natural geological activity.
The Practical Side: Logistics and Price
The total duration is around two hours, including transportation, safety briefing, mine exploration, and cave visit. The cost is $34 per person, which is quite reasonable considering the equipment, guides, and the overall experience. For travelers interested in geology or mining history, this offers a lot of value without it feeling overly commercialized or rushed.
The tour is private, providing a more intimate experience, and is available in English and Spanish. Booking is flexible — you can reserve now and pay later, which is convenient if your plans are still evolving.
More Great Tours NearbyWhat to Keep in Mind
While the experience is enjoyable and straightforward, it’s not suitable for everyone. The tour explicitly excludes children under 6, pregnant women, and those with mobility issues, claustrophobia, or certain age restrictions (over 70). This is mainly due to the confined spaces and physical nature of walking through tunnels. If you’re a confident traveler with no health concerns, this shouldn’t be an issue. But if you have any doubts, it’s best to assess your comfort level with small, enclosed spaces.
Why This Tour Stands Out
The combination of mine exploration and natural cave access makes this tour quite unique. It’s a genuine chance to see a significant part of Cantabria’s industrial past and natural geology up close, guided by experts. The fact that the mine was operational for nearly 80 years adds a layer of historical depth, and the guide’s storytelling makes the experience more engaging.
Plus, the reviews highlight the guide’s kindness and expertise, which elevates the experience. Many travelers appreciated how well the company takes care of safety and logistics — from providing all necessary gear to transporting visitors to and from the site.
It’s perfect for those who seek an alternative, less touristy activity and don’t mind a bit of underground walking. It’s also a fantastic choice for those interested in geology or mining history but want a manageable, guided experience rather than a DIY spelunking adventure.
Final Thoughts
If you’re in Cantabria and looking for an experience that’s practical, educational, and a little adventurous, this guided tour of the Udías mines and natural cave is a solid option. It offers a rare glimpse into the region’s mining past, all while being accessible and well-organized. The knowledgeable guides and safe equipment make it a trustworthy choice for curious travelers.
While it’s not suited for everyone — particularly those with health restrictions or who prefer more leisure-oriented activities — it’s an experience that can genuinely add a meaningful layer to your trip. Whether you’re a geology buff or just someone wanting to see a different side of Spain, this underground adventure is worth considering.
