Lüen-Castiel & Calfreisen
From the wild Plessur river all the way up to the Montalin
The three villages Lüen, Castiel and Calfreisen are spread out over three levels, from the bottom of the valley at the wild Plessur river all the way up to the Montalin mountain peak. The history of the three villages could not possibly differ more, but all three of them are the gate to the municipality of Arosa.
