Lago di Pietra Rossa

Located in the heart of the Aosta Valley, Lago Pietra Rossa culminates at 2553 meters above sea level at the end of the Vallon d’Arpy. Stuck between Becca Pugnenta in the northeast and Mont Cormet in the southwest, the lake remains an exceptional site thanks to the grandeur of the scene offered on the south face of the Chaine du Mont-Blanc, notably the Dent du Géant and The Grandes Jorasses. The first part of the ascent shares the same path that of Lago d’Arpy.

Ascent

The start of the itinerary is just in front of the Genzianella hotel. Take the wide path that leads into the forest. At the first crossing, leave on the right the direction “Colle della Croce” and continue on the left towards “Lago d’Arpy”. The road rises very slightly for about three kilometers to reach Lago d’Arpy. Continue on the left to follow a small path bypassing the lake from the north. A little further on, you cross a bridge overlooking the eastern shore of the lake. From there, the view is magnificent of the Grandes Jorasses. Continue to reach the south end of the lake and take the trail along the Torrent d’Arpy. Further on, you arrive at the foot of rocky terraces where the cascade of the Torrent d’Arpy flows. Turn right to go in the direction of the waterfall. The path then gets steeper; slabs along the way make the ascent easier. The footpath then crosses the Torrent d’Arpy and becomes harder to follow on passages that can be slippery; Luckily, the yellow markings make it easier to locate and give the right to reach the Lago di Pietra Rossa located a little further.
