The tour begins in Poschiavo, at 1,021 metres above sea level, and leads along the UNESCO World Heritage line of the Rhaetian Railway up to the Bernina Pass at 2,328 metres. It goes via the Cavaglia Glacier Garden with its glacial mills and Alp Grüm, which provides the first view of the eastern flanks of the Bernina massif. The wide, flat path along the Lago Bianco gives the opportunity to take a breather and loosen up their muscles for the further 1,000 metres of altitude up to Munt Pers at 3,207 metres above sea level - a climb that is rewarded with a breathtaking view of the Pers and Morteratsch glaciers.
