The Belvédère – Le Biol

After the last chalet (at the end of the tarmac road), walk up the mountain path to the Avals Valley to the place known as “Le Biol”. (1 hour). In the meadow downhill you can see the cornerstone of the old shelter destroyed by an avalanche in February 1999.

Le Biol –Portetta walls

Take a footpath on the left which soon takes you to a mountain pasture in the direction of the Portetta walls. After approximately 45 minutes, two paths go in different directions: left to the Col de la Grande Pierre and right to the Col des Saulces via Combe des Roches. Continue straight on to the footpath (unclear at the start of the path because of herds grazing) through a small meadow overlooked by rocky outcrops.

From Plateau des Glacerets to Brèche de Portetta

After passing the rocky outcrops, the path crosses the Plateau des Glacerets through piles of rocks. It’s an increasingly steep path until you reach the foot of the huge cliffs (Dents de la Portetta and Aiguille de Mey).
The footpath then goes up beneath the central ridge before turning left (north-facing) over a small wall to Brèche de la Portetta which is nestled between the two ridges the furthest on the left.

Aiguilles de la Portetta Tour

Visit Aiguilles de la Portetta: retrace your steps from Brèche then go under the central ridge and take an immediate left. An unclear path snakes through the scree between large rocks (bleak) leading to the heart of the Aiguilles then a pass called “Passage de Mey” where there are fantastic views of Pralognan and the Vanoise range.
