Description

Walk the trail of mule drivers, following the low dry stone walls as far as the wonderful Lac des Vaches. After which the itinerary continues to the Col de la Vanoise, at the foot of Savoie's highest peak, the Grande Casse (3855m).

Quite simply, this is one of the most beautiful hikes in Savoie.

After walking along the long stone walls that once marked the route of the salt peddlers, you magically cross Lac des Vaches.

Yes, you do walk on water! And here you are in the midst of a truly exceptional environment. Admire that great mineral fin on your right: it's the Aiguille de la Vanoise, a climb reserved for the very best climbers.

When you arrive at the recently refurbished refuge, you're at the foot of Grande Casse, the highest summit in Savoie, approaching 4,000 m, with its long glacier tongue. This is high mountain country, and it's not unusual to come across climbers preparing their gear for the next day's race.

This movie set will be your base camp for the night. So don't hesitate to leave the refuge for a few moments to gaze at the stars.

The next day, after enjoying the lakes and the sumptuous panorama, the descent is via the Circle de l'Arcelin. It's a different atmosphere that brings you back to civilization.

From the Fontanettes parking lot, the trail starts out in the forest alongside the ski slope to the Barmettes refuge. Continue along the path lined with low dry-stone walls and climb a grassy ridge to reach the Lac des Vaches flat. At the foot of the aiguille de la Vanoise, ford the lake on slabs. Further on, the trail climbs the moraine of the Grande casse glacier, a remnant of the Little Ice Age, and skirts Lac Long, leading to the Col de la Vanoise refuge, which you discover at the very last moment. Among the marmots, admire the impressive face of Grande Casse. Spectacle guaranteed!
