Fitness level
The ascent from Saint-Jacques to Mont Roisetta is one of the most demanding itineraries in the Val d'Ayas, gaining 1579 m to reach 3269 m. The walk starts from Saint-Jacques (1700 m), a hamlet of Ayas. The route climbs steadily through alpine pastures, crosses scree and boulder terrain and gains height at a consistent gradient before steepening in the upper section. The environment shifts with altitude: from green lowland meadow to the broad stony and rocky belts of high mountain, with the panorama progressively opening toward the Monte Rosa massif. The EE rating is justified by the elevation, route length and demanding terrain. Recommended from July to September.
