This route leads to one of the mountain pass escape routes used during the Second World War. It ran from the French settlement of Salau, in the River Salat valley of the region of Ariège, to the Catalan Pyrenees. Escaping Jews made their way from the Port de Salau pass to the village of Alòs d’Isil. Some of those stopped and captured along the way were transferred to the prison at Sort. The Persecuted and Saved project signposts the route, followed on foot, from the Refugi del Fornet mountain shelter to the Port de Salau pass. It is signposted and can be walked in both directions.
