Wonderful view from the pass. The downhill is quite steep at the beginning.

A very beautiful high mountain pass that allows us to access a breathtaking view of Mont Blanc. This pass connects Italy and France. Some technical advice: - On the Italian side, the path is rather well marked and is not very difficult and steep. It takes about twenty minutes to connect the Tachuy lake to the pass. - On the French side the path is just as visible but a little more difficult because it is a little steeper. It takes about an hour to access it from the Petit lake. - Be careful, potential presence of snow, even in summer (but in very reasonable quantity: we can get around...).

The Col des Chavannes (Italy Alti.2603m) offers one of the most beautiful panoramas of the Mont Blanc massif: accessible to all because not very technical

https://youtu.be/bq-e0bqLD9k https://youtu.be/eu_RPR989TI From the Rifugio Elisabetta, strenuous and steep from Courmayeur, but one of the most beautiful passes of my life. The descent to Les Chapieux is easy to manage on unblocked single trails.

The Col des Chavannes, located at almost 2,600 meters above sea level, offers a spectacular view of the majestic Mont Blanc massif and the upper Val Veny. You can reach it via a long but rather easy climb coming from the valley of the same name on the La Thuile side or even from Val Veny following a slightly steeper path, but still practicable for runners, if your legs allow it.

Segment from Rifugio Frassati (open only in summer) to Col de Malatrà.

Col de Malatrà, at an altitude of 2,925 metres, is an iconic place on the Alta Via of the Aosta Valley, with Mont Blanc standing out among the jagged rocks of the pass. For those who do the Tor des Géants, it represents the last great effort before the long descent towards Courmayeur. The terrain in this area is challenging and technical, but it is possible to hold on to the rope fixed to the rock to facilitate the passage.
