The Serra Albera is the name given to the eastern section of the Pyrenees, from the top of Portús to the Mediterranean Sea. It separates the great plains of l’Alt Empordà and mountains of Roussillon and is the current French-Spanish border. It is about 25 km long. In the southern part of the massif of Albera we find two very distinct areas: Western, vegetation of central European character with oak and beech forests and where you can find the last of the Albera cows, a native domestic breed. Eastern is more Mediterranean, with oaks and scrub vegetation and where remain the last populations of the Mediterranean tortoise.
