Difference in height uphill:
Go by car or by bus in the Vally of Sesto. Before the Gasthaus zum Klaus you will find a parking area, where the trail is starting. A little bit uphill it will bring you through a larch forest to the Tre Scarperi hut (open in winter-time). The valley offers a very nice view on the surrounding mountains. For the way back you can rent a toboggan and rush back to the starting point.
