Lago di Lod

Highlight • Lake

Beautiful lake which can be reached by following path 3 which starts from Chamois (in some sections, if you wish, you can opt for the carriage road). If you don't feel like walking, there is also the chairlift from Chamois.

Place Moulin Dam

Highlight • Monument

The Place Moulin dam is a dam in Italy. It stands in a side valley of the Aosta Valley northeast of Aosta in the municipality of Bionaz and there dams the Buthier, a tributary of the Dora Baltea, with an arch dam to form a reservoir. The dam, which was built from 1955 to 1965, was at that time one of the largest dams in the world with a height of 155 m.

Lago Blu

Highlight • Lake

The Blue Lake (il Lago Blu), also known as Lake Layet, is located in the Breuil-Cervinia region of the Aosta Valley and lies south of the Matterhorn. It sits at almost 2,000 meters above sea level, surrounded by larches. It is not a large lake, but what makes it so special is its bright color. Supposedly, the deep blue is the merit of both the algae and mineral content, and the clarity comes from the fact that it is constantly fed by freshwater springs.

Prarayer Hut

Highlight • Mountain Hut

The Prarayer refuge is located in the upper Bionaz valley, surrounded by majestic mountains, glaciers, woods, streams and lakes. The Matterhorn Tour passes here. The refuge overlooks a body of water, an artificial lake formed by the waters of the Buthier stream, which flows along the entire Valpelline. This lake is one of the largest in the Aosta Valley and offers spectacular scenery.

The most popular path to reach the refuge is from the south, via a mule track accessible to anyone, which follows the route along the lake. It's perfect for a relaxing, scenic ride, suitable for all levels. If you're looking for a more technical and fun challenge, there are other access routes that are slightly more challenging but equally rewarding.

At the hut, you can enjoy good, traditional dishes at really fair prices. In good weather, you can enjoy the view of the lake from the terrace. If the weather is bad, there's plenty of space inside, too.
