It is situated in the town and resort of Arosa, close by to the Obersee (one of the lakes in the vicinity).
The station is the upper terminus of the line and has a number of passenger facilities including a ticket office, shop, and cafe.
A 299m long tunnel takes the line under part of Arosa as it ascends to the station.
There is a large yard of freight/rolling stock sidings just beyond the station at the very end of the line, as well as a 2-road locomotive shed (essentially for shunters) at the lower end.
