The Swiss part of the route in the Appenzeller-Land and Zürcher-Oberland is characterized by hilly but extensive landscapes, green meadows, beautiful views of the valley and narrow to wide and well asphalted roads with little traffic. The landscape resembles in large parts that of a model railway in scale 1 : 1!

The tour first leads from Sonthofen via Margarethen, Hofen and Beilenberg to the old towns. Further on via Fischen to the Riedberg Pass. Via Balderschwang, Hittisau and Lingenau to Alberschwende and on to Dornbirn. From here to Hohenems and via Mader in Switzerland to Altstätten. Here not further over the Ruppenpass but left over Eichberg (turn right there) a small side road up to Appenzell. Here you can enjoy beautiful views of the Säntis. The route continues to Urnäsch. Turn left here and then immediately right again - without any signposting between two houses. Continue through the village uphill towards Schönengrund. Via Chäseren the tour continues to Dicken and Hoffeld. Just before the village you can admire a very beautiful railway bridge. Directly after the bridge, the route turns left via Ebersol to Necker and continues via Oberhelfenschwil and Ganterschwil to Lütisburg. The further course of the tour leads via Kirchberg to Dussnang and Sitzberg. Then again over a very narrow road up to Rotbühl and via Sternenberg down to Bauma.

Via Bäretswil, the route then climbs up the narrow asphalted ribbon to Bachtel-Kulm, where there is a great view of Lake Zurich and the surrounding mountains! The tour continues to Wald and from there via Oberholz and Fischental to Hülftegg (953 m). Then via Gähwil to Mosnang and Lichtensteig. From there over the Wasserfluh (848 m) to St. Peterzell. There turn right to Hemberg and via Bächli back to Urnäsch. From here via Hundwil and Haslen to Teufen and further via Bühler to Trogen. In Trogen turn sharp right towards Ruppenpass. Turn left there to St. Anton - always a worthwhile destination with great views down into the Rhine Valley and to Lake Constance. The last part of the tour then leads - this time with considerably more traffic via Berneck, Au and Hard to Bregenz. Via Langen and Scheffau to Weiler and Simmerberg the traffic becomes quieter again! The tour ends with the route via Genhofen, Kalzhofen and Immenstadt back to Sonthofen.
The tour is with a total length of about 380 km quite long, but worthwhile!
