Passo della Corna (Pas de la Corne) is an international high mountain pass at an elevation of 1.046m (3,431ft) above the sea level, located on the Italian-Franch border.
There’s no road on the Italian side. On the French side, the road is gravel, rocky, tippy and bumpy at times. Avoid driving in this area if unpaved mountain roads aren't your strong point. The pass is located on the edge of Mercantour park and links the Italian region Liguria and the French Alpes-Maritimes department. Only 4x4 vehicles. Very steep climb, with sections up to 20 %.
