The hike starts at Reichenau railway station, where you first cross the confluence of the Vorderrhein and Hinterrhein rivers and then walk along the Vorderrhein to Trin Station. After an initial stretch through the village, a beautiful hiking trail follows, always along the Rhine. In between there are always beautiful vantage points and good opportunities for breaks or barbecues. The hike is also ideal for families with small children, who can already hike on their own or are otherwise carried in a carry backpack (but not recommended for prams). At Trin Station you can optionally cross the Rhine on the suspension bridge.

From the Chur railway station, follow the national cycling route no. 2 (Rhine route) and cycle at the riverbank to Landquart. In Landquart, cross the Rhine river and later at Sarelli go left and follow the road up to Pfäfers and carry on to Vättis through a rugged basin with almost vertical mountain slopes.

The final ascent to the pass takes you away from the traffic through unspoilt, splendid countryside. Shortly past the Eggwald mountain restaurant, you leave the Canton of St. Gallen and enter Grisons again before reaching the pass summit.

When crossing from the Tamina Valley into the Rhine Valley, the great differences at either side of the water divide are amazing. The final descent to Tamins is a special treat, offering views of the confluence of the Vorder and Hinter Rhine. From Tamins take the national cycle route No. 2 (Rhine route) back to Chur (or return by rail from Reichenau station).

You have to do this tour once. For many cyclists it is one of the annual highlights. You experience the mighty Calanda massif from all sides. And who would have thought that it looks so rugged and jagged from the back. The route is extremely varied with the enjoyable start along the Rhine route. Via a side road with little traffic, you reach Pfäfers, where you cross the impressive Tamina bridge that spans the gorge. A long path through the Tamina valley follows via Valens, past the Mapragg reservoir and via Vättis finally to the Kunkelspass. The Überruf mountain inn stands at the top of the pass and offers the ideal opportunity for refreshments before the descent via the Forstrasse, at the beginning through tunnels hewn into the rock, leads down towards Tamins. The way back from there again follows the Rhine back to the Alpine City of Chur.

The Kunkelspass connects the Tamina valley (SG) with the municipality of Tamins (GR). It lies between the steep walls of the Calanda in the east and the mountain group around the Ringelspitz in the west. The narrow road and the tunnel on the Tamins side with the panoramic openings in the tunnel wall were built during the First World War. The Kunkelspass also forms the eastern entrance to the geological wonderland of the Tectonic Arena Sardona. At the pass near the Überruf mountain restaurant there is a seminar room with information about the UNESCO World Heritage Site. A telescope offers the opportunity to have a close look at the Ringelspitz and the Glarus thrust or the demolition niche of the Tamins mountain fall.

The Calanda massif consists of the four peaks Haldensteiner Calanda (at 2,805m the highest), Felsberger Calanda, Taminser Calanda and Berger Calanda (above Untervaz).

This circuit leads from Reichenau, the confluence of the Vorderrhein and Hinterrhein, along the Vorderrhein to Trin Station. Here you cross the Rhine over a 100 meter long suspension bridge (Punt Ruinaulta). A short, steep ascent follows. On the further way it is worth visiting the ruins of Wackenau and the viewing platform, which is slightly below the ruins and accessible from May to October. Through the Bonaduz forest you then return to Reichenau.
