Loop through the wild high valleys Val Curciusa and Val Vignun

From the village of Nufenen, follow the road down to the Hinterrhein. Then follow the hiking trail a bit back towards Splügen. After the bridge over the Areuabach - which we will follow closely - turn right at the barn and follow the trail up to Alp de Rog. Over numerous steps it goes up to the basin of the Val Curciusa. First along steep slopes, then through rocky steps and finally through the wide alpine meadows of the valley floor.  Time and again, the wild Areuabach reveals deep blue water basins. With a view of the Ghiacciaio de Curciusa glacier, pass the rifugio and continue up to the Bochetta de Curciusa.

From the Bochetta descend towards San Bernardino. Those who do not want to rejoin civilization stay high and follow the path again up to Val Vignun, where the next high valley can be discovered. On the left side of the valley, follow the stream to Strec de Vignun. From here, go steeply down to Alp de Rog. From there, follow the path back to Nufenen.

The Areuabach
The Areuabach is described by WWF as one of the few water gems in Switzerland. A swim stop is worth it!

Rifugio
Self-catered SAC hut in Val Curciusa: Rifugio Curciusa.

Length of the route
The route is very long. You can easily split the distance. The PostAuto connects San Bernardino and Nufenen very well in both directions.
