Dravuni Island is one of those little patches of paradise on a cruise itinerary to Fiji. It has a population of a mere 150 or so, but it swells to the size of a small town when cruise ships call. Situated in the Fijian island group of Kadavu, south of the main island of Viti Levu, it is an unspoilt, tiny tropical island measuring 2 kilometres long by about 0.5 kilometres wide. You could walk around it in no time, save for the rocky cliffs that come right down to the shore at both ends. You can, however, walk to its summit if you fancy a not-so-tough hike on a hot day.
