What to do around Whitstable area /villages en route

[KentnotClarke]

Hello what is there to do around this area please, we will definitely stop in Canterbury but I'm wondering if there is anything else to see? Special villages or nt properties?

The Ramsgate Tunnels are well worth a visit.

Not many NT or English Heritage places in this area, unfortunately.

If you are willing to drive a bit then Dover Castle (EH) is a worth a day trip.
