text: Is there a trail here in real life? If so, then it is correct to be mapped. OpenStreetMap maps what is reality, regardless of it being private property or not. This part of the trail is already mapped as access=no, so it is marked as not being available to the public.
  
  If there isn't a physical trail here, then it can be removed. I'm not a local, so I have no idea. If there is a physical trail here, then I believe the map data is correct.
