A hike between two valleys: from the Val de Zinal over a pass to the Moiry dam and reservoir, followed by a descent of the wild Val de Moiry and picturesque Grimentz.
Distance 14.4 km
Highest point2,856 m
Lowest point1,586 m
This hike starts at the top of the Zinal - Sorebois cable car, with a superb view of the Imperial Crown. The path climbs along steep slopes to reach the Sorebois pass, before descending into the Val de Moiry. Below, the Moiry dam holds back the turquoise waters of the lake, fed by the Moiry glacier, nestled at the bottom of the valley. Near the dam, a restaurant with a panoramic terrace, a via ferrata and guided tours of the interior of the dam await you. The second part of the hike is a long and beautiful descent through pastures and forests into the Val de Moiry to Grimentz.
The Anniviers Liberté pass offers a 50% discount on the funicular and free travel on the PostBus as well as certain activities.

Close gates after passing through.
Please be considerate to other trail users, and to the plants and animals.

For mountain hikes:
Take extra care protecting yourself from the sun at altitude. UV radiation can be exceptionally strong, even in cloudy weather.
Plan hike carefully: take into consideration fitness level of each participant, weather forecast and season.
Weather conditions can change quickly in the mountains, without warning. Appropriate clothing is therefore essential, along with adequate supplies of food and water. In uncertain weather, turn back in good time.
For high-altitude hikes:
Inform others of the route you plan to take. Whenever possible, avoid going alone.
Do not venture onto glaciers without a mountain guide.
Take note of the warning signs that point out the constant danger in river beds and along watercourses below dams and reservoirs: water levels may rise rapidly without warning.

Grimentz village (1,558 m)
The route begins at the top station of the Zinal–Sorebois cable car (2,438 m). From here, the trail climbs steadily up the south-western slopes of the Corne de Sorebois, but bypasses the summit itself for the Col de Sorebois (2,835 m).
From here, a steady zigzag descent leads down to the Moiry dam (2,250 m) where the restaurant with its sunny terrace offers a welcome stop for refreshments.
The trail leads across the crest of the dam before dropping down into the valley below. For the second half of the hike, the trail leads northwards, steadily descending the Val de Moiry, crossing the river La Gougra twice before arriving in Grimentz.
For a longer and more demanding hike, skip the cable car from Zinal to Sorebois and hike up instead.
