GPX track — verify on the ground before hiking
Fitness level
From Pont de Messuere (1425 m) the trail climbs toward the Corno Boussolaz (3023 m) via Lago Bringuez, gaining 1593 m over 6.4 km — one of the most sustained gradients among EE-rated trails in the Aosta Valley registry. Lago Bringuez at intermediate altitude is a glacial lake marking the transition from mid-mountain to high-alpine terrain. The Corno Boussolaz, a summit above 3000 m, offers a wide panorama across the alpine system between Val d'Ayas and the Swiss ridges. Season: June–September; stable conditions essential.
Along the way — you move facing the Monte Rosa massif and the Tournalin group. High up you enter the world of glaciers and scree, where the air is thin and the views open onto the 4000ers. It is for experienced hikers: steep or exposed sections, a sure foot is essential.
