Join us on an exclusive half-day adventure to explore one of the most extraordinary geological wonders in the world—El Soplao Cave. Nestled in the majestic Sierra de Arnero, this cave is globally celebrated for its exceptional speleothems—delicate and rare mineral formations that create a dreamlike underground landscape. Nature lovers and curious adventurers alike will find themselves captivated by this surreal subterranean world.
Your experience begins with a scenic little train ride that takes you deep into the heart of the cave. From there, enjoy a one-kilometer guided walk (conducted in Spanish) along well-lit and accessible paths, revealing dramatic stalactites, stalagmites, and crystalline structures unique to El Soplao. Designed to be inclusive, this tour is fully accessible to all visitors, including those using wheelchairs, making it a welcoming journey for everyone.
The adventure continues above ground as we head to the Pechón Viewing Point, where you'll be treated to sweeping views of the Cantabrian Sea and the Tina Menor estuary. This dramatic coastal landscape is perfect for reflecting on your journey and snapping some unforgettable photos. It’s a complete experience that blends the mystery of the underground with the natural beauty of Cantabria’s coastline.

The train was not working - which I can understand, but it would've been nice if we're informed in advance before I'm waiting an hour as this was the primary reason I wanted to do the tour. The tour guide speaks no English at all, so you have no context or information to make the experience more enjoyable. If you haven't seen such caves before, or you speak Spanish I highly recommend it, but as someone who has seen similar formations before it felt quite disappointing.

Fabulous experience, the separate location mine adventure was great but you need to be fit to do it. The cave adventure was very good fun with knowledgeable guides. You must book in advance for all tours as very popular.

Impressive and unique experience Guides are funny and friendly 1 min little train ride down to cave. Bring a jumper it's cold You will walk 2.4 km inside Parking outside Book your cave visit in advance if you don't want to wait. 15 euros per person Great panoramic view at the top in front of entrance.

What a visit! We couldn't recommend the Speleological Cave Tour more highly. It was absolutely fascinating, and our two guides did a terrific job explaining everything about the cave's origins and formation. Wearing the protective suit, helmet with a flashlight, and boots made me feel like a real explorer... or even a scientist! 🤣 We were also lucky to be in a small group of just seven people, all English speakers. So, although the tour is normally conducted in Spanish, our guides kindly did the entire excursion in English so we could follow along. They were not only incredibly knowledgeable, but also super friendly, helpful, and funny. Thanks again for this amazing experience! We’ll definitely be back!

1, the way up to the cave is very beautiful, full of sycamore trees. 2, Inside the cave is really cold, indeed. Remember to bring a jacket or a coat. 3, the cave itself is amazing of course, art of nature and time. But, yes, but, if you have already been some similar places like this, it wouldn't surprise you too much. For example, Reed Flute cave, Guilin, China, it is much bigger and more complicated. 4, it could be boring for children. We didn't think to bring Mei here before because we knew it could be boring for her yet, but her grandparents were here and they wanted to visit it so.....yes, we were right. Mei felt bored after staying in the cave for a while. A 6 years old kid, watching "stones " in the dark and cold..... not very good idea. 5, although, outside, the view is nice at sunset. And those cows are very calm. 😍 6, There are EV chargers.
