Path to Rifugio Prarayer and Lago di Place-Moulin

Highlight • Trail

The road to the refuge is a mule track accessible to anyone (even at
mothers with prams for children), the walk is also very beautiful
with mountain bikes.
The difference in height between the square where you leave the car (about 1980 m.s.l.m.) is
very modest (the refuge is located at 2005 m.s.l.m.).
The road follows the lake for about 6 km (45 minutes - 1 hour by road),
following a route full of streams and small waterfalls, to land at
refuge.

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.

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.

Larch that merges into the woods but is worth reaching, suggestive!
