The tour starts at the historic little town of Schwyz. The first 20 kilometres or so on a busy main road in the Muota valley are flat and perfect for warming up. You pass the world’s steepest funicular railway to Stoos, as well as the famous village of the weather prophets where, on entering the Hölloch (Europe’s third-largest cave system), a narrow pass road commences its ascent to the Pragel Pass – at 18%, the steepest section of the tour. From the natural idyll of Pragel, where you can taste alp cheese in the dairy or, higher, in the alp restaurant, you descend past pretty Lake Klöntal to Glarus. Now another flat stretch along the entire Linth valley brings you to Siebnen, where the Wägitaler Road leads towards Sattelegg, then down to Willerzell on glorious Lake Sihl. A cooling dip in the lake would surely be welcome! Following the left-hand side of the lake, the route visits Unteriberg and Oberiberg before dipping down to the Hoch-Ybrig area. A continual yet gentle ascent (14%) through attractive scenery brings you to the Ibergeregg Pass. Having arrived at the restaurant at the very top, almost at the foot of the two Mythens, you are ready for the thrilling descent and occasional fabulous views of the Schwyz valley basin, Brunnen, Lake Lucerne and Lake Lauerz.
