Sassal Mason, Mountain summit in Grisons, Switzerland

Sassal Mason is a 3,032-metre summit at the eastern end of the Bernina Range, between the Engadin and Val Poschiavo in Graubünden. It rises 202 metres above the surrounding terrain and stands beside Lago Bianco, overlooking the Bernina Pass. The nearest larger settlement is Poschiavo, about 8 km to the south.

The mountain formed through geological processes that shaped the alpine landscape over millions of years. In the 19th century, geologists studied the mineral and rock formations found in this area.

Sassal Mason overlooks the Bernina Pass, a route long used by Romansh-, Italian- and German-speaking communities. The pass marks the divide between the Engadin, where Romansh and German are spoken, and the Val Poschiavo, where Italian dominates. The nearby Bernina railway, opened in 1910, crosses the pass and links these valleys.

Hiking trails lead from Pontresina to the Sassal Mason mountain hotel at 2,355 meters, where you can stay overnight and eat. The hotel serves as a good base for exploring the surrounding peaks and valleys.

Sassal Mason rises 202 metres above the surrounding terrain, and its base is about 1.1 km wide. The nearest larger settlement is Poschiavo, roughly 8 km to the south, while the area around the peak is mainly grassland with only about 18 inhabitants per square kilometre.
