text: somewhere along this former Navacchio-Calci rail route, the footpath is (was) completely overgrown with The Big Bamboo and would need serious bushwhacking.  the footpath can be seen leading into the overgrowth from the north, and from the south there is an obvious well-used footpath almost to the (unmapped) viaduct, that then veers off to the east to a different unmapped path by an unmapped stream.  this path appears on posted maps, and in theory could be made free, but as of a couple months ago, a detour along the highway was needed.
