The Aosta Valley - Italy's smallest region
The Aosta Valley – Italy’s smallest region

Tucked up in the most north western part of the country is Italy’s smallest region, The Aosta Valley in Italian – Valle d’Aosta. Bordering with France and Switzerland, this region is characterized by it’s large mountains and dramatic valleys.

The Aosta Valley has a strong cultural identity, it also holds special status as an autonomous region and is bilingual French and Italian, however the majority of people also speak the fascinating dialect Valdôtain.

In Italy Aosta borders only with Piedmont sharing some spectacular surroundings. You can read more about Piedmont on Italy on Trail’s dedicated guide.

The Shape Of The Aosta Valley

A good way to begin to get to know the Aosta Valley is to think of it as the letter “Y” with the two valleys of Val Ferret and Val Veny respectively as the left and right top ‘arms’ – and with the main ‘stem’ as the principal artery, or valley where the river Dora Baltea flows, and where the main towns are located along with the motorway. Stretching out, like branches, are the numerous sub-valley’s in Valle D’Aosta, each with it’s own character and peculiarities.

The main valleys are:

1.Val Ferret
2.Valle del Gran San Bernardo
3.Valle di Saint-Barthelemy
5.Val d’Ayas
6.Valle di Gressoney

1.Val Veny
2.Vallone di La Thuile
4.Val di Rhêmes
6.Valle di Cogne
7.Valle di Champorcher

The Mountains – The Alps

Consider that the lowest point in the Aosta Valley is at Pont-Saint Martin, which stands at 343 meters above sea level, whereas over 30% of the Aosta Valley is on land that’s above 2500m above sea level, and a hefty 26%-28% is above 3000m.

In the Aosta Valley we can find some of Europe’s tallest mountains:

  • Matterhorn-Cervino highest point 4,478 m (14,692 ft)
  • Monte Rosa highest point 4,634 m (15,203 ft)
  • Gran Paradiso highest point 4,061 m (13,323 ft)And the tallest mountain in western Europe:
  • Mont Blanc that stands at 4,808 m (15,774 ft) above sea level.

Two ranges dominate this part of the western Alps: the Pennine Alps (Valais Alps,) and the Graian Alps, both extend across Piedmont and Aosta in Italy and Switzerland.

The Mont Blanc massif is part of the Graian range.

You can also find more of Europe’s highest mountains peaking at over 4.000 – Dente del Gigante, Grandes Jorasses, Breithorn, Roc, Aiguille Blanche de Peuterey and Lyskamm.

The Glaciers – Ghiacciaio (it)

Glacial and periglacial environments make up an important chunk of the region. The two most well known glaciers are the Miage and the Lys Glaciers.

Miage, at 3,892 m (12,769 ft) lies to the southwest of Mont Blanc and at 10km is Italy’s longest glacier and towards the southern part of the glacier lies Lake Miage.

The Lys glacier is on the southern part of Monte Rosa, and starts at 4248 m above sea level. (in Italian) is a website that’s been recording the Lys glacier’s status over recent years.
