Lago Bianco
Highlight • Lake
Reservoir on the Bernina Pass between the Valposchiavo and the uppermost side valley of the Engadine
The reservoir at the Bernina Pass is fed with glacier milk (glacial water containing silt). This gives the lake its milky, whitish color. Lago Bianco is also a watershed; the water flows eastwards into the Black Sea and southwards into the Adriatic Sea. The famous Bernina Express of the Rhaetian Railway, which is a UNESCO World Heritage Site, winds its way along the bank.

Lago Bianco
Highlight • Lake
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.

Trail Reviews
Today we drove to the 2,320-meter-high Bernina Pass. From there, we set off and walked around Lago Bianco. This hike is easy, and you can enjoy magnificent views of Piz Bernina, Piz Zup, and Piz Palü. The ridge of these mountains forms the border between Switzerland and Italy. From the opposite shore of the lake, you can enjoy views of Motta Biaca and Piz Lagalb. The RHB's red trains regularly delight the eye, bringing some variety to the scenery of blue water and gray rocks.
