Mouth of the Aragón river into Ebro river

The Aragón River, after the Ebro, is the most important river in Navarra. In the final Navarrese stretch, its channel fills with life the municipalities that advance south from Carcastillo to Milagro, where its waters flow into the point where we are.

This section of the Aragón River is included within the Special Conservation Area (ZEC) Low Sections of the Aragón and the Arga. Its abundant meanders and ravines, as well as the groves associated with this section, offer refuge and food for most of the forest and water birds in this area, highlighting the common bittern, the imperial heron and the gray heron, the white stork, the cattle egret, the marsh harrier, the black kite and the booted eagle.

The existence of small streams, inlets and islands and the construction of wetlands represent the best habitat for the presence of the European mink, one of the animals most at risk of extinction on the planet.

Once in the Ebro, its waters cross the Rioja until reaching Castejón, one of the Navarran towns with the largest population of storks, along with Cortes, Funes, Corella, Milagro and Tudela.

The GR-99 Route allows you to continue downstream and enter different groves of great plant and fauna richness in the Arguedas area until you reach the Ebro bridge in Tudela. In Fontellas we find a very charming place, el Bocal, where the path along the banks of the Ebro continues towards the towns of Cabanillas, Fustiñana, Ribaforada, Buñuel and Cortes
