Valle d’Aosta is a region in the north-west of Italy on the border with France and Switzerland. Located in the western Alps, it is known for the snow-capped peaks of the Matterhorn, Mont Blanc, Monte Rosa and Gran Paradiso.
Courmayeur and Cervinia are among the most important ski resorts.
The countryside of the region is dotted with medieval castles and fortresses, such as the Castle of Fénis and the Castle of Verrès, dating from the 14th century.
Valle d’Aosta is the smallest Italian region and is located in the middle of the Alps, which here are divided into the sectors of the Graian Alps and the Pennine Alps. It is surrounded by the four highest mountain massifs in Italy: Mont Blanc, which with 4,810.02 m [14] is the highest mountain in Europe, Cervino (4,478 m), Monte Rosa (4,634 m) and Gran Paradiso (4,061 m). The conformation of the entire regional territory is the result of the work of the glaciations, which excavated the main valley and the other side valleys. Glaciers now occupy only the highest peaks. Valley glaciers are still found, partially, around the Mont Blanc massif, mostly they are fossil glaciers, or covered by morainic boulders and vegetation on the terminal tongue, as happens for example in the Miage Glacier.
The region is crossed by the Dora Baltea, an important left tributary of the river Po, which marks its main valley from which numerous secondary valleys and their tributaries branch off, including the Dora di Valgrisenche and the Lys. The major natural lakes are Lake Verney in La Thuile, the Lower Laures Lake (fr. Lac des Laures inférieur) in Brissogne and the Gran Lago (fr. Grand Lac) in Champdepraz. [15] The Beauregard lake and the Place-Moulin lake are artificial reservoirs.
The most important border crossings are Colle del Piccolo San Bernardo and Colle del Gran San Bernardo, which corresponds to the tunnel of the same name. The southern part of the territory is occupied by the Gran Paradiso National Park (Parc National du Grand-Paradis), the first Italian national park established in 1922, to safeguard some species of endangered alpine flora and fauna such as ibex, chamois, marmots and ermines. The Mont Avic Natural Park (Parc naturel du Mont-Avic) is the first regional park in the Aosta Valley and extends between the Champdepraz valley and the Champorcher Valley.

Due to the orography of the Valle d’Aosta there are very different local microclimates even between valleys or nearby slopes.
Temperatures vary according to the altitude of the territory. At altitude there is an alpine climate, so summers are short and long cold winters alternate with temperatures that drop to -20 ° C and peaks even below -30 ° C at altitudes above 2,000 m. In the valley bottoms, continental climates are observed: in winter temperatures drop below 0 ° C; vice versa in the summer they rise even over 30 ° C with poor ventilation which accentuates the sensation of heat.
The rains in the Aosta Valley are scarce, especially when compared with the other regions of the Alpine sector, as the winds that blow most frequently are of western origin and discharge their moisture content on the western slopes of the Alps. The innermost valleys encased between imposing reliefs are very dry. To obviate the scarcity of rainfall, large irrigation channeling works called Rûs (pronounced “rü”, also in the plural) were built since the early Middle Ages and are still in use today.
