Between the Rifugio Pian Grand and the serviced Capanna Buffalora hut, the hiking trail climbs steeply to Fil de Bedoleta. It crosses several passes, traverses breathtaking gaps, wide valley basins and takes you past lakes such as the Lagh de Trescolmen or the heart-shaped Lagh de Calvaresc. Taking around eight hours, this stage requires good physical fitness.
