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

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.

A cute, bohemian refreshment bar, offering snacks and coffee, and an essential place to visit before, during or after a walk, there's never a bad time for coffee and cake.

Perfect alpine singletrack, winding along the steep valley side. The trail offers perfect views, which sometimes makes it very difficult to concentrate on the trail! This section is also used by hikers, so be sure to ride respectfully. Since this is an alpine meadow, expect to see a few cows wandering through the fields; wave to them as you pass.

A historic and iconic monastery perched on the border between Switzerland and Italy, it has existed as a hospice for over 1,000 years. Saint Bernard dogs, a symbol of Switzerland, were bred here for many years to rescue mountaineers in distress. The monastery is also located on the shores of the tranquil Great St. Bernard Lake, where many trails begin.
