Oddly enough, there appears to be some element of truth to this. While this IS a historic right of way, It is only recorded on the East Sussex side. Kent County Council don't have their part recorded. It is likely that this path could be recovered, though. I'd suggest looking into the Rambler's 'Don't Lose Your Way' campaign. In the meantime, I've updated the access rights on the map to match it's current status.
