Fantastically beautiful and a very long gravel road on a super sturdy gravel path. It's narrow, but that shouldn't be a problem. If you have to pass each other, you can do so via the adjacent forest road. It is also quite passable. These are not the only kilometers of gravel track in these forests on these amazingly tight bike paths. There is a larger network of decent paths. NB: please note, if you want to take a turn from this path, check if that is allowed. The other forest paths are often open to walkers, see small signs, "Open to walkers" with the footnote "By the way" (so apparently cycling not allowed).
