Anyone who likes to push/carry their eBike up the steepest paths when it starts to rain over muddy, slippery roots, coarse, moss-covered stones and fallen tree trunks will find the perfect tour here. The increase can be found in taking a three-year-old daughter in a child seat. Seriously: The tour is really beautiful, almost a fairytale forest. But by no means advisable with the eBike. Highly recommended as a hiking trail!

The pass, located at an altitude of 1,050 meters, offers you a magnificent view of the Alps and the Rhône valley. Like most of the peaks in this region, it sometimes allows you to see Mont Blanc.

The pass is located at 1050 m and offers you a magnificent view of the Alps and the Rhone Valley. As with most peaks in this region, Mont-Blanc is sometimes visible from here.
