La Vilette is the highest hamlet in the commune of Vaujany. Between the houses and the chairlift, there are delightful trails, the pretty Flumet stream, and superb viewpoints, notably of the Fare waterfall in the distance.

Very nice climb. The road to the top changes with the landscape and gradually becomes less good. No more loose gravel seen. No problem at all on the way up, but pay close attention at first on the descent. There was minimal traffic.

Very demanding climb but the landscapes are worth the detour!! Much less frequented than other major passes in the Alps.

The Col de la Croix de Fer culminates at an altitude of 2063 meters. It is the big neighbor of the Col du Glandon, another crossing point between the Maurienne and Oisans valleys. The Tour de France has used this pass 21 times. It is one of the most beautiful in France, a must-visit point for any mountain-loving cyclist!

It is one of the great discoveries of the French Alps in my last decade. It is not a mountain pass because it only has one road side. On foot (or even with a Gravel bike), once you reach the top, you can reach the Lac de Grand-Maison, connecting with the final stretch of the climb to the Col de Glandon or the Col de la Croix-de-Fer . The climb to Col de Sabot has a gradient of 1,253 meters, 14.5 km in length with an average slope of 8.9%. It is a very tough port. It has 2 parts that are very well differentiated in every sense: - The first, until reaching Vaujany (about 5 km) is a very wide road, perfectly paved, with some traffic and hardly any views of the valley. - The second is a very narrow road, with a lot of gravel, hardly any traffic and views of the alpine meadows. In a quiet environment where only the sounds of the mountain can be heard.

It is a spectacular climb from the valley, but it is true that from the town of Vaujany it is wonderful. The data show that it is a colossus of the Alps, with 1,283 meters of elevation gain, 14.5 km and an average slope of 8.9%. In the last 8 km the slope is even harder. The road is very narrow and very irregular. You breathe absolute tranquility. A MUST!!!

The Col du Sabot – 2100 m – is the highest point of the Isère passes and only 2000. From the pass the view is magnificent and you can see Lake Verney below.
