Although it's not recognizable from a distance, as you approach the entrance, you discover an opening to the other side. So it's not a "cave," but rather a hollowed-out hole. It's a very interesting visit if you're hiking nearby; don't let the distance and extra effort deter you from missing this opportunity.

Legend has it that a French abbot, fleeing the Revolution, came to these places, hiding in the cave. And they say that, from so much crying, his eyes became irritated in such a way that they caused him bad eyesight. But, on one occasion he noticed that by washing them with the waters of the fountain, his eyes healed. Hence the discovery of the virtues of the waters and the name of the place.

In the Bº de Rioz, in Sobremazas (Medio Cudeyo), behind the public washhouse, at the bottom in the rocks is a small cave where clear and crystalline water emerges and is where the source of the Cubón river is dated. The cave also gives the name to the small park that surrounds it, which has 3 wooden tables, a fountain and a small recreational park for young children and one of the Singular Trees of Cantabria: El Castaño de Rioz.
