Peñas de Aia - Aiako Harria

Peñas de AiaBetween the Urumea and Bidasoa rivers stands the imposing massif known as Peñas de Aia (Aiako Harria in the local Basque language). A mountain range of spectacular beauty with an unmistakable silhouette, it is also a site of great geological interest, being the only granite massif in the Basque Country and the oldest mountain in the region.

Its nature reserve also includes an area known as the “cordal de Urdaburu-Añarbe”, which contains a series of wonderful oak and beech forests, the fascinating Landarbaso Caves and the lovely clear water Añarbe reservoir.

Nevertheless, if Peñas de Aia is known for anything, it is for its rich and varied wildlife. Atlantic salmon can still be found today in the Endara irrigation channel, and the species has also been reintroduced into the River Urumea. Pyrenean desmans and European minks can also be found in the area. Vultures and Egyptian vultures can often be seen circling overhead. The pasturelands which surround the high part of Endara are home to Montagu’s harriers and the rocky outcrops provide shelter for crag martins, alpine accentors and rock thrushes.

Urdaburu forest is home to wild cats and roe deer, both originally from the neighbouring mountains of Navarra. As well as a number of other typical bird species, of special interest are hawfinches, since this is the only area in the Basque Country in which these brightly coloured birds can be found.
