Entrance to the Soplao cave, 1 hour

Can you imagine discovering a cave full of minerals? If you consider yourself an adventurer and want to explore what lies beneath the Arnero mountain range, this experience is for you.

The exterior of Cantabria is beautiful for its unparalleled coastal landscapes and its green mountains, but its interior is also beautiful. In its subsoil there is a cave considered unique for being located in the center of Cantabria, specifically in Celis.

Popular for its most impressive formations and minerals in all of Europe, this cave was discovered by a series of miners at the beginning of the 20th century, in 1908, while working in the mines of La Florida. They decided to name it "El Soplao" because of the air current that is produced when passing from one tunnel to another with less oxygen.

During the tour you will see between shadows and lights, minerals such as eccentrics, dog tooth crystals, stalactites, stalagmites, columns, cave pearls and lava flows. Don't you think it's incredible?
