The A-8 motorway twists through Cantabrian mountains before straightening into France's A63. This route from Santiago de Compostela to Sète spans 880 km, crossing three distinct biomes: Atlantic Galicia, the Basque green belt, and the Mediterranean Languedoc. At the halfway point, Bordeaux marks a climatic shift where ocean humidity yields to southern sun.
