The access point to this path is absolutely not present – there is a barbed-wire fence leading into undistinguished woods. The OS map indicates a right of way, but extensive searching yesterday revealed no sign of either the OS path or the indicated OSM path. This (long ago) used to be a path to a ferry, but I suspect it has not been used in decades (perhaps since the construction of the airfield ca. 1940). It is currently utterly impassable due to undergrowth and fences. I have a GPS trace and hope to look further into this soon (examining local rights of way maps) and I intend to edit accordingly.
