Start the tour in tranquil Castrisch and follow the official Rhine-Velo route no. 3. The road climbs only slightly, which is perfect for easing your legs in. In Valendas, you have the opportunity to fill your water bottle with fresh mountain spring water at the largest wooden fountain in Europe. After Carrera, turn off onto the road to Brün and continue up to Imschlacht. The road and the views are marvellous. A tip: you can fortify yourself with a portion of mountain cheese, salsiz or a nut tart at the Maiensässbeizli. Then it's down into the Safiental valley. Another highlight is the spectacular panoramic road along the Rhine Gorge, where the rock faces of the "Swiss Grand Canyon" tower 300 metres high. From Bonaduz, you cycle along side roads to Chur. The section between the capital of Graubünden and Lavin in the Lower Engadine is covered comfortably on the Rhaetian Railway. From the Lower Engadin village of Lavin, your muscle power is required again. The route to the stage finish takes you along a finely gravelled path via Guarda to Scuol. The bright turquoise-coloured Inn flows below you. A completely different landscape awaits you in the Lower Engadin. The sunburnt stables of the Surselva give way to houses with colourful paintings. The art of "sgraffito", the traditional stucco technique of the region, is still practised by only a few in the valley. And in Scuol, not only mountain spring water but even mineral water flows from the fountains. Simply gschpunna.
