Weissfluhjoch, Alpine summit in Grisons, Switzerland

Weissfluhjoch is a summit in the Plessur Range in the Swiss canton of Grisons, sitting at 2693 meters. It stands at the point where three valleys meet and the terrain shifts from open meadows to rocky ground and snow depending on the season.

In the 1930s, a mountain railway called the Parsennbahn was built to connect Davos directly to this peak. That link turned the area into a destination for skiers and hikers from many countries.

The name Weissfluhjoch refers to the white snow fields that cover the peak for much of the year. Standing at the top, you can look out over three valleys at once: the Landwassertal, Prättigau, and Schanfigg.

The summit is most easily reached by the Parsennbahn from Davos, which runs year-round and operates in nearly all weather. At this altitude, wind and cold can pick up quickly, so warm layers and sturdy footwear are a good idea.

About 500 metres southeast of the summit, at 2,540 metres, lies the Weissfluhjoch test field (5WJ), where weather and snow conditions have been recorded daily since autumn 1936. It is the only site at this altitude worldwide with more than 80 years of continuous daily snow-depth and new-snow measurements.
