The trails in the Upper Gran San Bernardo Valley are not located in protected areas where pets are prohibited: dogs are allowed on all hiking trails in the valley, provided they are kept on a leash.
The regulations of the Autonomous Region of Valle d’Aosta and municipal ordinances require that dogs be kept on a leash at all times, with the leash not exceeding 1.5 meters in length. The Barasson, Menouve, Citrin, and Merdeux valleys are pastures grazed by herds of cattle raised for Fontina DOP cheese and by flocks of sheep guarded by herding dogs. Unleashed dogs can trigger defensive reactions from livestock, lead to incidents with herding dogs, or cause harm to local wildlife (marmots, chamois, and roe deer).
On rocky and scree-covered sections at high altitudes, such as the ascent to Col Malatrà (2,925 m along Alta Via No. 1) or the route to the Molline Bivouac (2,415 m), sharp scree can cause abrasions and cuts to dogs’ paw pads. Above 2,200 meters, springs and streams are scarce: be sure to bring an adequate supply of water and a bowl. Whether dogs are allowed in the dormitories of alpine huts depends on the manager and must be confirmed in advance.
Recommended itineraries and hikes are described on the Summer Outdoor and Routes & Trails pages.
