We have some great coastal landscapes in the south east of england too - especially around south and east kent and sussex - and all a short drive from London. Let me know if you are planning on coming this way and I'll give you a few specific locations - maybe will be able to act as tour guide - you never know!

Mind you - I've just got back from a week in Cornwall - and there are some amazing coastal landscapes there - especially on the North coast.

Enjoy your trip.
