On the Ospizio Bernina we start our hike to the southernmost part of Graubünden. First briefly along the Lago Bianco and then very easily uphill in about an hour to the mighty viewpoint Sassal Mason. Between glacier and mountain lakes lie the round "Crott" stone houses and the view into the Puschlav, the Palü glacier and down into the Cavaglia glacier garden is unique. From Sassal Mason we continue to Alp Grüm. The RhB stop is at 2091 metres and from here you have a wonderful view of the Palü glacier, the small Palü lake and into the southern Graubünden valley of Puschlav. The hike continues to the Palü lake. After hiking along the lake follows a steep descent to Cavaglia. Here we will not miss a visit to the glacier mills and the glacier garden.
We officially end our hike after visiting the glacier mills in Cavaglia. You can comfortably get back to the Bernina Pass with the RhB. If you still want to hike to Poschiavo, you follow the hiking trail for a little more than an hour to Poschiavo. Poschiavo, with its narrow streets and beautiful village piazzas, conveys Mediterranean feelings in the midst of the alpine scenery.
