Moiry Dam and guided tours / Grimentz

Road closed until June

The imposing Moiry dam, 148 metres high, dominates the end of the Vallon de Moiry. As you take the 8 km road linking it with Grimentz you are struck by the visual spectacle of this huge concrete structure. But once on top of the dam, you discover a stunning panorama and a varied range of activities and sights, including :

• A restaurant
• A via ferrata
• A glacier
• A mountain hut
• Mountain pastures
• Climbing facilities

The Moiry dam and surrounding area are only accessible in summer, when the weather conditions allow the road to be kept open. However, it is possible to get there on foot once the good weather returns after the snow has melted.

All the technical information relating to the Moiry dam, the power plants at Mottec and Vissoie and the La Gougra hydroelectric plant can be found on the website
