The river Piedra, the reservoir of La Tranquera and the Monastery of Piedra make the district of Nuévalos strikingly beautiful.

Nuévalos sits next to the river Piedra, at the end of the reservoir of La Tranquera. The limestone cliffs cut by the river Piedra and the vegetation which grows along its banks make it an excellent place to see a large number of birds of prey and birds which live among the rocks. Likewise, in the reservoir of La Tranquera and among its huge extension of reeds a great many herons, cormorants and ducks can be seen, depending on the time of the year. The reservoir has been exploited as a place for water sports. And there are excellent places for fishing, both on the reservoir and on some stretches of the river Piedra.

The Monastery of Piedra, meanwhile, is one of the most important tourist centres in Aragón. It is a Cistercian monastery converted into a hotel which has an exceptional park, where water, rocks and vegetation are the chief characters.
