The Orrido di Bellano is the main tourist attraction of the town and one of the most important of Lake Como. This is a natural gorge created 15 million years ago by the erosion of the River Pioverna and the Adda glacier which, over the centuries, have shaped the rock into gigantic potholes, dark ravines and suggestive caves. The narrow canyon can be visited thanks to a system of footbridges anchored on the high walls overlooking the water, perfectly illuminated in the evening where the charm of the place takes on different nuances, and that recently have been extended to reach the large waterfall located further upstream.
