I've finally resurrected and finished a mini guide that I started when I was unemployed ages ago - just in time for the bank holiday! It covers the Southern part of the Culm coast, basically the stretch around Bude (including Northcott, Sandymouth, Widemouth and others).
I've put it on ISSU here:

It should also be going up on Javu and probably Rock and Run fairly soon.
Many thanks to the people who helped in various ways - much appreciated.
