Malachi's Cove by Anthony Trollope — Read

On the northern coast of Cornwall, between Tintagel and Bossiney, down to the very margin of the sea, there lived not long since an old man who got his living by saving seaweed from the waves, and selling it for manure. The cliffs there are bold and fine, and the sea beats in upon them from the north with a grand violence. I doubt whether it be not the finest morsel of cliff scenery in England, though it is beaten by many portions of the west coast of Ireland, and perhaps also by spots in Wales and Scotland. Cliffs should be nearly precipitous, they should be broken in their outlines, and should barely admit here and there of an insecure passage from the summit of the sand at their feet. The sea should come, if not up to them, at least very near to them, and then, above all things, the water below them should be blue, and not of that dead leaden colour which is so familiar to us in England. At Tintagel all these requisites are there, except that bright blue colour which is so lovely.

But the cliffs themselves are bold and well broken, and the margin of sand at high water is very narrow -- so narrow that at spring-tides there is barely a footing there.
