I found a map at https://webapps.kent.gov.uk/countrysideaccesscams/standardmap.aspx 

But it only describes it as a track and when clicking on it says "nothing found at this location". That's not enough to confirm it as a right of way. 

The map implies that it's possible to search by Path Code and that path code might be searchable elsewhere to confirm its official status. 

What do you see on the ground? Is the path gated? Are there any signs that confirm its status as a public path? Are any of the gates locked at any time?
