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!
