The Aosta Valley has an alpine climate with cold winters and cool summers. During the winter months, the avergage daily temperature can easily reach zero centigrade and can fall further during periods of intense cold. Fortunately, the variation in altitude between the mountains and the sunny valleys which they surround and dominate creates many different areas with pleasant micro-climates. Summers are fresh and windy but the rain level can be quite high. In the winter snow falls over the entire region, and in the summer rain falls in the valleys with snow continuing to fall on the mountain tops.



With an area of only 3,266 km², the Aosta Valley is the smallest region in Italy and one third of this area is above 2,600 metres in altitude. It borders Switzerland to the North, the French departments of Savoie and Haute Savoie to the West and the Piedmont Region to the South and East.

By car

The Aosta Valley is very well connected by road. Turin can be reached directly using highway A5 or via the by-pass in Santhià which connects to highway A4. The regional highway system is in very good condition and trafic is generally fluid, although it can become more intense during the week-ends. The region’s internal road network is also well developed with access to the side valleys open all year round. The Aosta Valley can also be reached from France or Switzerland through the Mont Blanc and the Gran San Bernardo tunnels, by taking National Roads n°26 and n°27 respectively. All areas of the valley fall within a maximum radius of 130 km from the centrally located city of Aosta so most locations in the region can be reached in no more than 1 hour.
