The Val di Rèzzalo is, from a naturalistic and scenic point of view, one of the most interesting, although not one of the most frequented, of the Alta Valtellina. It offers different opportunities: from the simple walk in an open, bright and typically alpine setting, to the most demanding hike to the Passo dell ‘Alpe, from the mountain bike route, made possible by an almost entirely cyclable route due to the presence of a military road, to the ski-mountaineering route, which offers a long and unforgettable opportunity to slide from the point of arrival of the Valfurva ski lifts to Fumero, in the lower Val di Rezzalo. All in a symphony of colors and lights that recalls much more famous valleys, but not for this reason more beautiful.
