And there is a lovely children's novel, The Twenty-One Balloons, set amidst Krakatoa and its fabulous diamond mines. (You never did know about those, did you? Or the intellectual colony set up there in the 1880s? Hmm....)
Shame this was the first comment. Krakatoa is a wild, wonderful place. At the edge of the crater a panorama opens up before you: the new Anak Krakatoa cone, Sebesi Island and the Gulf of Lampung, the Straits stretching away to Java behind the rim of the 1883 crater. Behind you the pine forest of the shoreline screams for recognition in its precarious location. It's a powerful and inspiring scene that, despite my boughts with chillies in a country like Indonesia, I don't feel inclined to trivialise.
