From the parking area of Le Buet, take the path signposted “Refuge de la Pierre à Bérard” across the parking lot of Le Buet.
The trail goes through the village of la Poya and then climbs into the forest.
In 15 minutes, bar of the Eau de Bérard cascade. Follow the torrent on the right bank as far as an junction allowing you to cross the stream (one leaves the refuge of the Pierre Bérard trail) towards “Tré-les-Eaux” then follow “Les Granges”. Before arriving at the Granges (restored alpine chalets), the trail leads leftwards to Tré-les-Eaux (facing the mountain).
It runs through a bit of forest and then the steep climb runs in the open in sharp bends.
After this climb, one tackles a long crossing, less steep, to the bottom of the valley “La Gouille au Bouc”, a wide coomb at the foot of the Buet mountain. The trail winds through a corridor lined with rocks and scattered fir trees. Nature in its purest form. Progressing toward the bottom of the coomb, the landscape is more barren, made of rock knobs. Why not picnic in this relaxing place far from the world.
The return is done the other way around using the same itinerary. Superb views in this direction of the Tour and Argentière glaciers, the Grands Montets and the Drus.
For very good hikers, there’s a possibility to continue for a circular route towards Col des Corbeaux (Ravens pass) (2,602m) (allow 7h30 without picnic stop), From Ravens pass, take the path to the right which leads to the Col de la Terrasse (2,645m). From the Col de la Terrasse, the trail tumbles through fallen rocks to the Refuge de Loriaz (2,020 m). See hiking N° 16 for the description of Loriaz refuge chalets and their exceptional viewpoint on the Mont-Blanc massif.
