This trail is very beautiful and much less traveled than the trail on the eastern shore. In early summer, you'll often find a snowfield roughly halfway along the trail that must be crossed.

Lago Bianco, Bernina Pass at 2234 meters The Lago Bianco is a reservoir at the Bernina Pass and is located in the area of the municipalities of Pontresina and Poschiavo. The lake is located directly at the pass at 2234 meters above sea level. The Lago Bianco is bordered by two dams on its north and south sides and is around three kilometers long and about 800m wide. When filled to its maximum, the depth of the Lago Bianco is over 50 meters. The reservoir on the Bernina Pass is fed by various mountain streams and glacier water, while the Cavagliasch in particular leaves the lake. The whitish, somewhat milky-looking Lago Bianco gets its name (in German "White Lake") from the inflow of sand and glacier water. The Bernina Hospice (Ospizio Bernina) is located on the western shore of Lago Bianco, and the Rhaetian Railway's train line - the Bernina Express - also runs directly along the shore. The Bernina Pass road is also located on the western side, but not directly on the lake shore. In cold winters, the lake can freeze over and in some years the beautiful black ice forms. When the reservoir is then opened by the authorities, nothing stands in the way of ice skating on Lago Bianco. Text / Source: Schweizersee.ch https://www.schweizersee.ch/lago_bianco_pontresina/

Breathtaking mountains around the Bernina Pass. Very worthwhile: excursion and overnight stay at 3000 m Diavolezza.

The Lago Bianco has 2 dams. On the one hand, the water flows northwards over the Inn, the Danube into the Black Sea and on the other hand southwards over the Po into the Adratic Sea.
