Chenaillet is characterized by its two types of rocks, magmatic and sedimentary, that one usually observes at the time of deep-sea diving to less 2000 meters.

This solid mass, makes the object of many excursions and studies on behalf of international geologists.
Moreover, the richness of these rocks, is the ground of a great floristic diversity, not less than 327 species and under species are present.

One can in particular observe:

A village dominated by the fortification
Of share its geographical position, at the Italian border, Montgenèvre was the witness of the last conflicts.
Thus, to defend and observe various fortifications were built on the field of Montgenèvre.
Most remarkable of them without any doubt the FORT OF the CHABERTON, also named is the fort of the Clouds. Culminating with 3135 meters of altitude, with a French slope and an Italian slope, it is most of all.
Built between 1900 and 1914, the top had to be undermined to level it and thus lower its 6 meters height. One should not not less than 300 civil workmen and the minor sappers to build this technical and human prowess, made up of 8 turrets. Those form the visible part of the building, whose whole is mainly underground. But on June 10 of 1940 Mussolini declares the war in France, and on June 21, French, located in the forts at the neighbourhoods Chaberton and its 320 men bombard. One will need only 57 shells to muzzle the fort of the clouds. In 1957, the fort is disarmed and makes now the goal of ballade, where one can observe some vestiges.
The FORT OF the GONDRANS, built as from the XIXème century is a whole of batteries and blockhouses, dedicated to defend the heights of Briançon since the Collar of the Angels.
The FORT OF the JANUS, built between 1886 and 1903, on the top of the same name. A 900 meters long underground work which prolongs the Maginot line, was added between 1931 and 1937. Museum in preparation as well as restorations. Currently, all these fortifications are a goal very justifying for a ballade day labourer.
