13 · 4.7–18.2 km · +300–1427 m
Valpelline
The wild Valpelline: Oyace and Ollomont sit at nearly the same elevation, but Col Brison at 2520 m demands over 1100 m of climbing with views to Mont Vélan and Grand Combin on the Swiss border.
Valle del Gran San Bernardo
Over Col Champillon (2709 m) with panoramic views from Mont Blanc to Gran Paradiso, followed by a long descent to Saint-Rhémy-en-Bosses in the historic upper Grand Saint-Bernard valley.
Valle del Gran San Bernardo
A steady climb through the Merdeux basin to Rifugio Frassati at 2540 m, the last overnight stop before tackling Col Malatrà (2925 m), the highest pass on the entire Alta Via 1.
Val Ferret
The final AV1 stage: the Val Ferret balcony trail with Mont Blanc and Grandes Jorasses always in sight, ending at Courmayeur, Italy's alpine capital.
Bassa Valle — Mont Mars
From Perloz hill the trail climbs through Lillianes forest and into the Mont Mars Nature Reserve, where Rifugio Coda at 2280 m opens the view to the high valley.
Mont Mars — Valle di Gaby
A high-level traverse between Mont Mars and the Barma Lakes: a skyline path linking two historic huts across a landscape of peat bogs, glacial slabs and end-of-summer bilberry.
Valle di Gressoney
The longest stage in this sequence: 18 km of solitary ridge walking above the Lys valley with Monte Rosa views, ending in the Walser town of Gressoney-Saint-Jean.
Valle di Gressoney — Valle d'Ayas
Crossing Col Pinter at 2777 m is the highlight of this stage: a wild pass between two alpine valleys where Monte Rosa dominates the entire eastern horizon.
Valle d'Ayas
From the ridges above Champoluc to Rifugio Grand Tournalin with the Matterhorn always in view: high-mountain terrain with sweeping panoramas over the Ayas valley and its pastoral landscape.
Valtournenche
The great descent: from Rifugio Grand Tournalin losing over a thousand metres to the valley floor of Valtournenche, passing through the scenic plateau of Cheneil with Matterhorn views.
Valtournenche
The shortest stage on the entire AV1: 4.7 km of sustained climbing from Valtournenche to Rifugio Jean Barmasse on the shores of Lago di Cignana, in preparation for the hardest day ahead.
Val Ferret
Balcony trail along Val Ferret facing the Mont Blanc massif. Quite possibly Italy's finest panorama.
Val di Cogne
From the heart of Gran Paradiso National Park to an alpine lake surrounded by ibex. A classic.
