We speak (and sing) about "The White Cliffs of Dover" but the most spectacular stretch of white cliffs is nowhere near Dover, but 70 miles west, on the Sussex coast between Eastbourne and Seaford- which is where the line of the South Downs meets the sea. The cliffs have names- Beachy Head, The Seven Sisters, Seaford Head. At Birling Gap a downland valley allows access to the beach and you can walk about beneath them.
I just checked to see if the white cliffs were on the UNESCO World Heritage list- and they're not. They're not even on the list of places we'd like to see added. I think this is a quite extraordinary oversight.
