What was the Route of the Pyrenees?
The road through the pass holds a much grander history; it was once part of the legendary Route Nationale 618 (RN 618), an ambitious, 450-kilometer French national road famously dubbed the "Route of the Pyrénées" because it traversed numerous high-altitude passes that are now iconic in the Tour de France. This pivotal artery served as a major thoroughfare that provided a scenic link between the Atlantic Ocean at Saint-Jean-de-Luz and the Mediterranean Sea at Argelès-sur-Mer. Although the entire route was down-graded in 1970 and subsequently split into departmental roads (the D918 and the D618), the path still carries the heritage of one of France's most important and challenging mountain routes.
