From Leuk, the route follows the right-hand side of the Dala valley to Chällerflüe. Top up your energy with coffee and croissants at the restaurant in Birchen before tackling the 500-metre ascent that follows. This ascent includes the "Chäller" crossing, where you will have to push your mountain bike for about 350 metres. Although the path is quite wide and secured with steel cables, it helps if you are not subject to vertigo. But it's well worth the effort: once you reach the top, you enjoy a breathtaking view of the entire Rhone valley. The panorama will quickly make you forget all the effort you have put in previously. After a well-deserved rest, comes a 1,100-metre descent on high level singletracks down to Varen. Stop off in this famous wine village to visit a wine cellar, or continue on to the historic town of Leuk, where the imposing town hall with its castle offers another opportunity to round off an exciting day.
