The white cliffs of Dover is famous but there is nothing like seeing something like this in person on a beautiful, blue sky day! The cliff-side walk is really stunning. Best to pay for parking up near the cliffs. You could search for parking close to Dover town but then you would have to climb up the hill to get to the cliffs!
I kept my eyes peeled on the water for some whales or dolphins but I didn’t see any but is that France I see? The high location also gives a stunning view of Dover port.
Stretch your legs on the drive home from Dover by stopping in Canterbury for a look at the magnificent Canterbury Cathedral. Tickets are about £15.50/adult or you can time your visit for a service so you pop your head in for a quick look for free!
