Colle delle Chaberton is a high mountain pass at an elevation of 2.674m (8,772ft) above the sea level, located in the French Alps, in the département of Hautes-Alpes.
The road to the summit is totally unpaved. It's called Strada militare dello Chaberton, also known as Strada militare di Val Morino or Fenils-Chaberton road. This road starts at the village of Fénils in the Italian Susa Valley. In present days the runway is extremely poor and at an altitude of 2,300 meters is no longer passable.
This carriage road was built between 1896 and 1898 by Italian troops that built an artillery battery on the summit that pointed towards France, in particular at the town of Briançon, and the pass to Italy over the Col de Montgenèvre. It's one of the highest mountain roads of the country. This old military road used to be the highest unpaved road of the Alps. However, the runway is no longer continuously driveable. It's driveable only, in parts, by authorized cars since 1987.
