From the Valle dei Molini, North-West of Bezzecca, following an easy forest road you get to Bochèt de Zori which joins up with path 459 bis. From here you start to climb along a mountain path which runs along or near the crest, which linked, towards the end of World War I, the bottom of the valley to the Italian outposts of Monte Vies. All along this stretch you can enjoy interesting views over Valle di Ledro and Val Concei. Then you come to Malga Vies, where you meet itineraries 415, 424 and 423, which continues uphill to Monte Cadria.
