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.

The legend of Lago Blu says that long ago, where the Blue Lake is today, there was a small house where a family of shepherds lived. One night, a poor traveler came to visit and knocked on their door, seeking food and shelter. The young shepherdess turned him away, but her son could not bear the thought of this selfish act. He tried to give the traveler his own bowl of milk, but his parents did not allow it and gave the man a bowl of dirty water instead. The parents even punished their son for going against their will and sent him out into the forest that very night to collect wood. He managed to collect a lot of wood without being attacked by wild animals, and when he returned home, he was horrified to find that his house was no longer there. A lake had swallowed him and with him his entire family. As the boy grew up and started his own family and village, they were known to be friendly, hospitable people who always welcomed strangers.

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.

Very charateristic wooden hut. It's a single room with toilet service on the outside. That alone is worth the ascent, like the Matterhorn view on its own. You can even sleep there, better if equipped.
