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.

The Cueva de El Juyo is located in a sinkhole developed in the upper part of Igollo (Camargo), which is accessed by a small track that ends in the cavity. The cave contains an impressive Lower Magdalenian site (between 16,500 and 14,000 years old) -one of the most outstanding in the Iberian Peninsula-, and was the scene of the excavations and research carried out by Joaquín González Echegaray together with Leslie Gordon Freeman -prehistorian and professor from the University of Chicago

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.

Well, the truth is that I didn't find any cave, and I did take a few turns around the theoretical point. Not worth it.
