50 minutes. The Paratge Natural d’Interès Nacional de l’Albera constitutes the border separating France from the Alt Empordà region to the north. It is a significant massif with important natural, landscape, pre-historic and Romanesque heritage. The Serra de les Salines is the natural continuation of Albera beyond El Coll de Pertús (in La Jonquera), and is also an area of natural interest. It is a clear example of the contrast between the landscapes of the Empordà and the mountains of the eastern Pyrenees.
