Nuévalos looks out over the La Tranquera reservoir, a few minutes from the monastery. After the park, walk over to the village and down to the water's edge: it is the same River Piedra you have just seen in waterfalls, now calm, with the village above it. You can fish from the shore with an Aragón licence.

The reservoir

According to reports from the Ebro Hydrographic Confederation, La Tranquera lies in the municipality of Carenas and regulates the waters of the River Piedra. It is a moderately sized reservoir of very irregular shape, with two clearly marked arms. It has a capacity of 84.26 cubic hectometres, a flooded surface of 530 hectares, an average depth of 15.8 metres and a maximum of 41. Its water is used mainly for irrigation, for the public water supply and for generating electricity, so the water level varies with the season.

What to do

It is a short, free walk, with no ticket and no opening hours, ideal for the end of the afternoon. You reach the shore from the village or from the accommodation beside the water, and from the shore you can fish with the Aragón fishing licence. With children, it is the place to skim stones and stretch your legs after the car.

For longer walks, Monasterio de Piedra suggests the GR-24 in its surroundings, which leaves Nuévalos towards Ibdes and Jaraba, and the Mesa river canyon, a protected Natura 2000 area with vertical walls more than 100 metres high and plenty of birds of prey.

Where to sleep by the water

The Hotel Río Piedra is next to the reservoir, and the Lago Resort campsite, on the road to Alhama de Aragón, looks over the reservoir from the hillside and is known for its easy access to the shore for fishing. Note that Lago Resort is closed from 25 October to March 2027.

Combining it

La Tranquera is the quiet counterpart to a day at the park. In the low season, enter the park at 9:00, visit the monastery afterwards and go down to the reservoir in the last light. And if you fancy some hot water, the Alhama thermal lake is towards Alhama de Aragón.
