The charms of Moiry Lake

Lacy de Moiry is an alpine reservoir located above the charming little Swiss village of Grimentz. The lake is perched on a rocky alpine ledge at an altitude of 2350 metres, offering impressive views of the surrounding mountains.

Often described as an emerald lake because of the colour of its waters, Moiry Lake is framed by the mountain peaks of Garde de Bordon, Corne de Sorebois and Sasseneire. Listed as a UNESCO World Heritage Site, the majestic Glacier de Moiry towers over the lake from the Pointe de Mourti.

There are many ways of enjoying these natural wonders, through hikes, excursions or even themed visits, making it a popular destination for nature loves and adventurers.

Outdoor activities at Moiry Lake

The Moiry dam offers a multitude of outdoor activities, so you can take in its unique panorama from various angles. One of its unmissable excursions is a hike around Moiry Lake, which takes around 2 and a half hours and can be done in two different ways: following the route to the east of the lake or the trail to the west.


The region offers a variety of hiking routes, particularly from Zinal. From the Corne de Sorebois, you can make your way to Moiry Lake by following the steep mountain paths. If you’re looking for a shorter walk, while higher in altitude, set off from the dam towards the heights of the lake. A visit to the nearby alpine gardens will also give you a chance to appreciate the alpine flora typical to the region.

The history of Moiry Lake and its geological walks

The arch dam, which stands 148 metres tall, was built with the main aim of generating hydroelectric power by holding back the waters of the River Gougra. Completed in 1958, this construction also contributed to the development of the Val d’Anniviers region, by improving access routes from Sierre.

The construction of the Moiry dam is an example of how the region’s natural resources can be used to support local economic development, providing a renewable source of energy and improving access to areas that were previously isolated.

Moiry Lake is a perfect place for discovering the different stages of geological history in the Alps. The geological trail “Moiry: from Europe to Africa”, marked out by small green squares, is a real journey through time. Come and discover the history of the land, the ancient ocean of Téthys and the old African continent by exploring the main groups of rocks.
