Passing under the imposing covered viaduct that leads to the tunnel marks the beginning of the toughest part of the climb: the gradients become more demanding (though never prohibitive), the fatigue accumulated over the previous 20 km takes its toll, and the winds from Switzerland begin to lash you... you're officially in the high mountains, after all, that's why you came here. If the day is one of the worst, with strong winds from the pass, these last 10 km will be a nightmare, but the beauty and majesty of the landscape will more than make up for even the most intense of efforts.

The highest road pass in the Aosta Valley and a place that has always fascinated the writer for its thousand-year history, the austere Mauritian hospice and the profound beauty of the landscape.

This climb is something incredible: it doesn't have difficult gradients but it's long, very long, endless. You reach a point where you almost hate it: you've been cycling for well over an hour and still can't see the summit, you're running out of energy and the wind keeps whipping your face, you'd like to throw your bike away and say "Enough! I'm stopping here"... but it's only for a moment, because you're the one who chose to face it and you knew perfectly well what you were getting into; you set off again with more grit than before and tackle those last few km of road with all your remaining strength. And then you enter the tunnel, there you start to realize you've made it, you come out, follow the road that turns slightly to the left and, as if in a dream, the lake appears. You reach the top and think about how many people throughout the centuries have traveled this road: Salassi, Romans, monks, migrants, Napoleonic soldiers... you realize you are in a place where History is dense and nature is stunning, and there you can only love this hill

An intense and very impressive climb. Over 11km you have to overcome around 850 meters in altitude. The roads are narrow and winding. There is little traffic. The splendor of colors in the larch forests is particularly impressive in autumn. Not an easy but highly recommended alternative to the main road in the valley.

The austere buildings of the Hospice of Great St. Bernard are situated in a rocky pass through which an icy wind almost always blows, on the edge of a lake that is frozen for an average of 265 days a year and where winter lasts almost eight months. For nine centuries, the Canons Regular of the Order of St. Augustine, who settled here at the instigation of St. Bernard of Menthon, have maintained a tradition of helpfulness and hospitality. Travellers who wish to relax for a while in this peaceful place are welcome all year round.
