Hi Jonathan, if you don’t mind basic facilities I’d recommend Carne camping on the north coast near Morvah. Really reasonable price in a rural setting with basic toilet block and no frills. Just check their seasonal opening times. Its location is equidistant from Bosigran and Sennen which are the must-visit Cornish crags, both are so breathtaking and atmospheric (Bosigran is mostly multipitch if you’re happy with that, excellent tea room just down the road from the parking too!) Sennen area would fulfil your surfing needs (Sennen surf centre based there). On a holiday visit I personally wouldn’t bother with the Culm coast further north in Devon and Cornwall, conditions are more changeable and it’s more sketchy adventure-style trad, unless that’s your thing of course.
Devon-wise, I would recommend Dewerstone for some Dartmoor climbing history, and hound tor/ haytor for some classic moorland cragging, though they’re touristy areas of the moor they are great and have loads of nice picturesque pubs and villages nearby. Great for walking too if you get rained off (likely at some point!). Chudleigh also has some good limestone trad. North coast (Bude) etc for plenty of surfing. Can’t comment on campsites around Devon as it’s where I grew up but sure there’s plenty of good ones. Hope this helps! Drop us a direct email if you want to chat further.
