If you enjoy uphill riding, there's hardly a better way in Switzerland to pack in so many meters of elevation in one climb. On this variant from Chippis to the Barrage de Moiry, you'll break the 2,000-meter elevation gain mark.
Amazing descent coming from Pas de Lona / Basset de Lona with a breathtaking panorama onto Lac de Moiry and its glacier. Chunky gravel at first, it smoothens out as you go down.
