Geography
The Valle d'Aosta is a small valley, the valley of the Dora Baltea river, with some smaller side valleys. It is in the middle of the Alps, surrounded by four of the tallest mountains throughout Italy and Europe:

 Mont Blanc; height:  (), the highest mountain in the Alps.
 Matterhorn (German), Monte Cervino (Italian) or Mont Cervin (French); height:  ()
 Monte Rosa; height:  (), the second highest mountain in the Alps. 
 Gran Paradiso; height:  ().

In the Valle d'Aosta, a region with many mountains and close to the borders with other countries, the mountain passes are very important. Even though now there some tunnels, the passes are important. They add a historical and geographical perspective which is important to tourism and tradition.

The main mountain passes between the Val d'Aosta and other valleys are:
 The Little St Bernard Pass (French: Col du Petit Saint-Bernard; Italian: Colle del Piccolo San Bernardo), between Savoie, France and the Valle d'Aosta;
 The Great St Bernard Pass (French: Col du Grand Saint-Bernard; Italian: Colle del Gran San Bernardo), between Valais, Switzerland and the Valle d'Aosta;.

The southern part of the territory is occupied by the Gran Paradiso National Park, created in 1922 to protect plants and animals in danger of extinction.

The valleys were made by glaciers moving at a time when the entire region was covered by them. Currently, glaciers occupy only the highest peaks.

The Dora Baltea () river flows along the whole Valle d'Aosta, from the northwest to the southeast; it is  long and is a tributary of the Po river.
