Meetings organised by a history teacher between students from the Tristan Derème middle school in Oloron and former escapees from France via Spain, during the Second World War, gave rise to the idea of marking the path taken by some of them.
Thus, in June 1999, a ninth-grade class of students and their teacher crossed the Pyrenees for the first time via the Lhers plateau and the Col de la Cuarde. In Hecho, Manuel Ricoy and Roger Albero, who had traveled this same route on 3 July 1943, were waiting for them.
In 2004, the Freedom Trail, duly marked by the Pyrenees National Park, was officially inaugurated by the Prefect of the Pyrénées-Atlantiques region, the mayors, and the Ministry of the Armed Forces.
