Trail along Lake Mauvoisin

Highlight (Segment) • Trail

It goes through tunnels on a trail next to the lake. After a short climb, it goes downhill and with a bombastic view of the lake! It is worth making the driveway to the lake!

The highest road pass in the Aosta Valley and a place that has always fascinated the writer for its thousand-year history, the austere Mauritian hospice and the profound beauty of the landscape.

The hut has been successfully modernized, combining old and new. Not much of the old hut's charm remains, but everything is now more spacious, well-designed, and bright, including a wonderful lounge with panoramic windows. The hut can also be reached as a day trip by taking the bus to the dam and walking around the lake—with a coffee stop at the Chanrion Hut.
