It is worth visiting the hermitage of Santa María de la Hoz, in the town of Tobera. To do this, we will cross a medieval bridge of Roman origin that spans the Molinar riverbed. The temple, almost embedded in a large rock, dates from the 13th century, features both Romanesque and Gothic elements, and has a portico with arches that offers good views of the surroundings. At its feet stands a second, tiny hermitage from a later date – the 17th century – which houses an altar dedicated to the Cristo de los Remedios.

It is the upper viewpoint of the waterfalls, but not the best (in my opinion).
