Moiry Dam
Grimentz, Switzerland
A curved dam above Grimentz holding a milky-turquoise lake, with a road on to the foot of the Moiry Glacier. The narrow road is open in summer; walks from the upper car park reach the glacier lake.
The Moiry dam above Grimentz in the Val d’Anniviers (Valais, Switzerland) holds back the Lac de Moiry. The wall is 148 metres high and has been in operation since 1958. The lake shimmers turquoise to emerald green, and the Moiry Glacier lies at the head of the valley.
A road leads to the dam crest at about 2,250 metres, and you can also drive along the lake to the glacier at about 2,350 metres. The road is open from the end of June until the first heavy snowfall (as of October 2026); check the weather and road conditions before you set off. Walking around the lake takes about two hours, and paths from the lake also lead to the Cabane de Moiry and the Becs de Bosson hut. There are restaurants at the lake. In summer, guided tours of the dam are offered on request (about 1.5 hours).
