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.
