Valle D'Aosta
It is the smallest, least populated and least densely populated region in Italy. It is located in the north-west and the territory is completely mountainous (like Trentino-Alto Adige) and has the highest peaks of our peninsula: Mont Blanc (4,810 meters), Monte Rosa (4,634 m, the maximum height reached in Switzerland, however) ), Matterhorn (4,478 m.) And Gran Paradiso (4,061 m.). P>
The main valley that gives its name to the region is formed by the Dora Baltea, the most important river, which receives the numerous tributaries that form the remaining valleys. p>
