Best route from Boxhill to Canterbury?

So gonna ride to Canterbury via Boxhill and don’t want to die of boredom on M25 - M2

Anyone got any suggestions as to a good route?

Looking at map its either A25-A20-A252-A28

OR A25-A21-A262-A28.

Any other suggestions will be appreciated preferably with a biker friendly cafe enroute for a breakfast

TIA

Route two is longer, possibly slower, but also more fun. The other route is OK, although you need to avoid Maidstone even if it means a bit of the M20.

Cool thanks
