9France–Italy: Mont Blanc
Towering at 4,807 meters, Mont Blanc forms a natural border between France and Italy. The breathtaking alpine scenery of the Mont Blanc Massif includes glaciers, jagged peaks, and lush valleys. Adventure seekers can traverse this border via the Mont Blanc Tunnel or by hiking trails like the Tour du Mont Blanc, offering views of both sides’ unique charm—France’s sophisticated Chamonix and Italy’s quaint Courmayeur.
