Piz Lunghin, Mountain summit in Grisons, Switzerland

Piz Lunghin is a 2,780 m summit in the Albula range, in the Swiss canton of Grisons, northwest of Maloja and above the Maloja Pass. It belongs to the Lagrev group and lies entirely within the municipality of Bregaglia. The north side falls in the Parc Ela protected area, and the Lägh dal Lunghin, source of the Inn, lies below the peak.

The Maloja Pass at the foot of this summit has served as a crossing point between Lombardy and Graubunden since Roman times. Over centuries, merchants and travelers passed through here, shaping the communities that grew on both sides of the Alps.

The Senda Segantini, a hiking trail near the summit, is named after painter Giovanni Segantini, who painted the landscapes of this region in the late 19th century. Along the trail, information panels explain which views and scenes inspired his work.

Two main trails reach the top from Lägh da Lunghin and Pass Lunghin, with the final stretch passing over rocky ground and a narrow gully. Sturdy footwear is a good idea, and checking the weather before setting out is always worth it, as conditions can shift fast.

The triple watershed lies not at the summit but at the Lunghin Pass, 600 m away at 2,645 m. From there water reaches the North Sea via the Gelgia, Albula and Rhine, the Mediterranean via the Mera, Adda and Po, and the Black Sea via the Inn and Danube. The Rhine runs 740 km to the North Sea, the Po 275 km to the Adriatic, the Danube 1,560 km to the Black Sea.
