In reply to henrycusack:
the nature of the coastline is highly unsuitable to DWS; the rocky bits are rocky under the water as well; there is great fun to be had coasteering (or messing about on the rocks as we called it when kids), but no DWS. The decent climbing crags (Bowden / kyloe) are only 20 / 30 mins away from Craster, and you'll enjoy the coast itself much more without thinking of anything beyond bouldering on some of the outcrops / small cliffs. and the rocks are bloody sharp.......
From craster, walk south past Howick to boulmer, or north past the castle and head up to newton / beadnell (how far do you want to go........) for some spectacular coastal walks.
I would also very strongly advise against trying to climb on the farnes. Quite apart from the logistics of getting there, its a nature reserve with huge breeding colonies of puffins and grey seals. And the water is effing freezing, with very interesting currents....
So; coastal walks, and a short drive to classic crags. Still a brill place for a holiday, and that area is probably my second favourite place on the planet.
