This time I went about 100-200 meters, until I reached some stairs with something resembling railings. I didn't go any further because I was alone, without signal, and I was afraid of going any further.

Located above a cave, this hermitage is next to the river and the old road that connected with the Cantabrian coast and Duranguesado. It is located next to a climbing area.

Impressive cavity, until a while ago you could go through. They have recently put up a sign, warning of the danger of contracting Q fever, and the passage is prohibited.

In the rainy season, you may not be able to cross the tunnel without getting your feet wet. But it is impressive to find this at the beginning.

One of the most beautiful caves I have ever seen. First because of the location, second because of the small challenge of not getting lost to get there, and thirdly because it is super cool: a huge mouth and easy to travel (with a flashlight) a good stretch. Absolutely recommended.
