The line starts at Davos Platz station and runs first through the southern part of the Davos countryside.
The line crosses the Landwasser for the first time on a bridge outside Davos Platz.
A short time later it passes the siding to the waste disposal facility and a little later the former halt of Islen, before the line runs to the south on a long straight section next to the river.
A siding branches off to the gravel works before Frauenkirch station and then the line changes to the western side of the river on another bridge.

The line crosses the Landwasser again on another bridge near Glaris and crosses Landwasserstrasse shortly later.
After Glaris station, the valley becomes increasingly narrow and the line reaches the wild Zügenschlucht (gorge) shortly after Davos Monstein and passed through it using various tunnels and bridges.

The Wiesen station is far below the village it is named after.
Immediately after the station, the line runs over the 210 m (690 ft) long and 89 m (292 ft) high Wiesen Viaduct, which is Rhaetian Railway's largest stone bridge.
 The line then traverses the remaining section to the Filisur station, far above the deep Landwasser gorge on a slope.

A total of 14 tunnels with a total length of 4,200 metres and 28 bridges are passed between Davos Platz and Filisur, which makes the line technically extremely interesting, not least because of the famous Wiesen Viaduct.

Immediately south of the Wiesen Viaduct there is also a Hipp turning disk (Wendescheibe) at the edge of the track, which, however, is no longer used as a railway signal for rail operations.

A parliamentary initiative launched in 2008 to connect this line with the Arosa Railway is currently not considered a priority by the Grisons government in the light of tight financial resources.
