text: Paths are difficult, largely because the usual map renderers display everything path/footway with the same barely visible red dashed line, so you can't distinguish a major highway and something really sketchy.
  
  If people use it, I would mark it. 
  informal=yes
  is a useful tag to indicate a sketchier path.
  I often use trail_visibility=bad if the
  path is not obvious (may be not the case here).
  surface=dirt
  indicates that it's a ground path.
  
  designation=XX
  helps distinguish the PRoWs, which are rendered differently in some maps e.g.

  Up to you to decide and close the note!
