Why Hike Sorebois to Lac de Moiry via Col de Sorebois
This hike crosses the ridge separating the Zinal and the Moiry valleys at the Col du Sorebois, a scenic pass with panoramic views of the peaks towering above the east side of the Zinal Valley, the rugged summits rising to the west of the Lac de Moiry and, in the distance, the high-peaks soaring above Arolla.
The ascent to the pass travels through the pastures of the Sorebois ski area marred with ski apparatus. After crossing the Col du Sorebois the trail drops steeply into the Val de Moiry and then traverses the steep slopes on the east side of the valley, high above the Lac de Moiry. This segment is accompanied by views of the ridge, punctuated with minor summits, along the west side of the Moiry valley. For much of the traverse the glacier-clad peaks at the head of the valley are hidden by the slopes of the west face of the Garde de Bordon protruding into the valley.
As the trail approaches the head of the valley grand views open to the Moiry Glacier, spilling down the slopes of the Grand Cornier. Near the head of the valley the trail drops down to the valley floor. The hike can be cut short at this point by taking the bus back to Grimentz and Zinal.
At the head of the valley hikers can opt to visit the Moiry Hut with splendid views of the Moiry Glacier. This side trip climbs over 1,300-ft. on a 4.0 mile round-trip hike to the hut. Alternatively, hikers can walk to the Barrage de Moiry (dam) on a pleasant trail traveling along the west side of the lake. At the dam, regularly scheduled buses return to Grimentz and Zinal.
