Mount Infernet (2400 m) dominates the walled town of Briancon (citè Vauban), at the confluence of the valleys of the Durance and the Guisane, French Western Alps.

The fortress located on top of it is a real eagle's nest, from which you can enjoy a panoramic view of 360°, unique for his beauty and color.

In June 1940, during the battle of the Alps, hidden among the rocks of Mount Infernet, was placed the French Artillery observatory, to destroy with the fire of his mortars the Chaberton Fortress (6th Battery of the 154th RAP [Regiment Artillerie de Position]).
Is precisely the case to say that this mountain has always been very careful eyes on Italy. With this pleasant excursion, walking in the footsteps of history, we will search for these old eyes, now closed in peace now.

Getting There.

From the town of Briancon (Durance Valley, France) follow the signs to the fortress of "Trois Tetes", is a military zone, but in the absence of army tutorials, you can park your car in the large open space in front of the fortress. From this point starts the road of the Forts, ancient dirt path that leads up to the top of Mount Infernet. It will be crossed only by walking or mountain biking, it is absolutely forbidden to transit to off-road vehicles.

The Trail.

Route Description.

The road of the guns is a very long path that goes back with wide or narrow switchbacks across the mountain, the slope is never greater than 12% (a common feature of all the military roads to facilitate the transport of heavy weapons).

Along the way meet all the fortifications built by the French over the centuries to protect their borders, "Trois Tetes, Randouillet, reduced the Andourn". (not to be visited inside)


At about midway through a ruined village, military: "The Seyte", characterized by small barracks dating from the early twentieth century.
Within which you can still see the inscriptions and drawings left by the military over the years. In June 1940, this village was used as a store of artillery.

Continuing on we pass along the hillside on the slope in which was built the telephone military system (it is a position Maginot type).
A little further along, hidden by a small wood, are the locations where they were placed the 280 mm. mortars(those who fired on Chaberton). There are two small brick houses with the roof floor uncovered and a large ditch that contained the base of the mortar.
These structures were built by Italian workers in 1939 that they went to work in neighboring France.
Would have been enough question them to the return to Italy, to find out what the French were preparing against the Chaberton.But the Italian secret services did not do it!
From here you can enjoy an excellent view over the valley of Cervieres and the Pic de Rochebrune.

Continuing on the military road we reach the part of the mountain now completely devoid of trees, bend at the third last, completely hidden in a pile of rocks, there is the observatory of artillery (the eye of the mountain), from which the commander Miguet directed the fire of his mortars in June 1940. From eleven thousand meters with an accuracy and a devastating effect. The slot of the observatory fits only Mount Chaberton.

The Infernet Fortress is the only one that you can visit. It is open and abandoned.

On the Rampart...a marvelous view!

It is a perfect place to set up a base camp with tent and watch the beautiful sunset and sunrise on the Haute Alpes.

Continuing further along the military road, you can visit the abandoned village of the Cochette and, ascending the ridge of the Ombilic, reach the Gondrans. The road continues down the gentle slopes that in winter become wonderful ski slopes, until you reach the village of Montgenèvre.
