This may be true but it is probably illegal and unwanted.

Those paths have a history. They have been retagged as access=no after the forest guards complained that some users were passing here. We should not encourage illegal stuff through OSM.

I see the following note on this path: "This path has been created by users following the fence but is not authorised by the forest management. It crosses a forest reserve where it's forbidden to walk/cycle off the official paths, hence its existence and use is not permitted."
