The Valley of Grauson

The panoramic view is extremely vast and the floristic richness is among the most varied and exclusive in all of the Valle d’Aosta: from the hamlet of Gimillan to the tip of Arpisson, from the promontory of Tsaplana until the East within the Valley of Grauson, ending practically at Lake Coronas. A variety of habitats which include high-altitude Alpine pastures, wastelands, moors, springs, lakes and marshlands and which contribute not only to warranty an elevated degree of biodiversity but also confer upon the Valley its landscape of truly unique worth. This territory is well-known for the conservation and protection of rare species such as the Aethionema thomasianum, the Potentilla multifida, the Campanula alpestris and the Sedum villosum, all identified in very few other Italian sites.

A naturalistic attraction of great importance which, together with the rich and typically Alpine fauna, animate this area.

Activities

  • Hiking

    All trails are in excellent condition, as they undergo periodic maintenance.

    It is possible to reach the Grauson Valley by the trails which leave from the parking lots located in the hamlet of Gimillan. Classical destinations include  Grauson – Vieux (2.270 m) and Grauson - Neuf (2.540 m).

    The first is a small village to the left of the Grauson torrent, while the second is located on the left of the Lussert torrent; in either case, you will encounter many restructured rural buildings and many pastures still in use. To the North, you will find the 4 lakes of Lussert, located under the Col des Laures between approx. 2.700m and 2.900m in altitude: the trail is easy, but its distance is rather long, and thus difficult to undertake in a single day without prior training.

    At the height of the hamlet of Pilaz, you will find lovely waterfalls, an ideal spot to pause and observe the landscape.

    Another trail (marked 3, 3B, 3C and 8), recommended for trained hikers, brings you to Tsaplana (2.678m), from which you can enjoy a superb panoramic view on the valley which houses Cogne.

  • Snowshoe trekking

    In general, the area is subjected to avalanches: it is therefore recommended to snowshoe trek only along the circular trail which surrounds Truc Cretetaz. In any case, please consult the snow and weather forecasts before your departure.

Discover the site

The best season to admire the blossoming of the Valley’s unique species coincides with the months of July and August. Although not highly frequented, the site’s elevated naturalness recommends itself only to hikers in small groups, aware and careful not to disturb the equilibrium of this Alpine ecosystem.


Behavioural conduct rules

We remind you that you can contribute to the preservation of these sites by following these simple rules:

visit the site on foot, with skis or snowshoes; avoid using motorized vehicles, boating equipment, hang-gliders, para-gliders or similar; mountain bikes and horseback riding are permitted only in specific authorized areas (external to the site): please respect hikers;

How to get there

By car

The municipality of Cogne can be reached by the S.R. 47 regional road, taken from the S.S. 26 road, at the height of Aymavilles. Proceed along the entire length of the valley until you reach Cogne, and then continue towards the hamlet of Gimillan, located North of the chief-town, where you can park your vehicle.

Buses are requested to stop only for the time it takes to embark or disembark passengers, and then to proceed to the area equipped for them at the entrance of Cogne, next to the cemetery.

By bus

The Aosta – Cogne busline makes 7 daily trips and reaches the centre of the municipality of Cogne. From here, paying shuttles depart and go to the hamlet of Gimillan, with a single daily frequence (increased during periods of high touristic affluence).
