Barmasc - Mont Zerbion

Mont Zerbion is one of the most rewarding viewpoints in the Aosta Valley. Starting from the hamlet of Barmasc (1898 m), the trail climbs steadily across open pastures and high-altitude meadows to the summit at 2722 m. The 810 m of elevation gain over 3.9 km are demanding but never technical, making this a classic hike for fit walkers. From the top, the panorama spans 360 degrees: Mont Blanc to the west, the Matterhorn and Monte Rosa to the north, and the Gran Paradiso massif to the south-east. Summer grazing is still active along the route, and encounters with Valdostan cattle herds are common. An early start is advisable to maximise visibility and avoid afternoon thunderstorms.
