From Pieve di Ledro take the asphalt road which goes up to Doss di Pur where the itinerary 456 starts. A steep cement path takes you to the Fienili di S. Martino, a summer grazing area with a small alpine church dedicated to Saint Martin. Continue along the path half-way up the southern slope of Monte Corno and Cima Casèt till you reach the beautiful grazing place of S. Anna and Malga Giù.
