Here's a great trek in the heart of Val Formazza, in an extraordinary scenery. To complete the trip in one day, you have to be well trained. The route we followed was chosen for the greater safety of snow conditions, passes through the pasture Battelmatt and the glacier of Chamois and involves passing a steep gully about 45 degrees that is evaluated BSA (good ski-alpinist); otherwise you may choose to break it in two days, taking advantage of the many shelters in the area (Refuge Busto Arsizio, Refuge 3A).
