High-altitude trail around the lake of Moiry at 2,500 m.a.s.l. The hike through the spectacular alpine landscapes shaped by glaciers promises beautiful views of the dam with its lake, the wild Moiry valley at the end of the Val d'Anniviers, and the glittering Moiry glacier.
This panoramic hike takes you around the turquoise-blue Moiry reservoir. If you’re interested, you can learn more about electricity production on a guided tour inside the dam before or after the hike. A fascinating detail: thanks to a network of tunnels, the lake collects water not only from the Moiry valley, but also from neighbouring valleys. On the way down into the Rhone valley, you pass three hydroelectric power plants. The energy produced covers the electricity needs of more than 120,000 Swiss households. Start and finish of the circular hiking tour is the dam. From here, the steeply winding trail zigzags up the eastern slope above the lake to around 2,370 metres, after which the trail branches off to the south. First uphill, then alternatingly up and down, you reach the end of the lake and cross the alpine pastures of "Fêta d'Août de Châteaupré", before the trail descends steeply to the glacial waters of the Châteaupré lake. Here, the mountain stream Gougra is also crossed, which feeds the reservoir with the glacial water of the Moiry glacier. It is located about five kilometres south of the lake below the Pointe de Mourti. After crossing the river, the trail climbs again over the glacial moraine to just under 2,500 metres. Now you continue across the flank on the other side of the valley. Along the way, the small lakes "Lac de la Bayenna" and "Lac du Louché" invite you to take a break before the final descent. Of course, the break can also wait until you get to the restaurant back at the dam, where a terrace with a lake view awaits. Climbing fans won’t miss out either and can enjoy the via ferrata to the left of the dam.
