I suppose it depends how far you want to travel, I know it's a long way from Pem/shire but I can recommend North Cornwall round the Tintagel area, some good sites to be found ,again I can recommend the cc site, Trewethett farm a friendly ,well, maintained site with coastal walks to boot.
then there's also the east coast of Yorkshire ,there you've got , Robin hoods bay, Whitby , Filey , Scarborough , Bridlington etc all of which have coastal walks of some description or another, for coastal walks though ,personally I would opt for Robin hoods bay, here again I can recommend Middlewood farm holiday park, as well as coastal walks the North York moors and places like Goathland ( Heartbeat country) are also with-in easy reach.
hope this all helps
