It is worth getting here to have some beautiful views of the Deva river valley. In the town of Cicera you must take the detour along the north path that leads to the hermitage of Santa Catalina and from there continue a few more meters, highly recommended!

The Ojo de la Fuentona is the source of the homonymous river in the town of Ruente, a very quiet and picturesque place surrounded by a very peculiar legend. Given its intermittency, the river sometimes dries up completely and in the past it was said that an anjana (good witch) lived in the Eye who used to have some whim and could make the water stop emanating there.
