Anafi is the last Cycladic island to the south-east. It is triangularly shaped, 151 sq km in area, and 145 nautical miles from Piraeus. It is a semi-mountainous island with Vigla (584 metres), Kalamos (459 metres) and Agios Ioannis Theologos (350 metres) as its highest peaks. It is traversed by many small torrents, such as Megalos Potamos, Kalambakes, and Modi. Anafi has been an object of research in the past for geologists and mineralogists. Its subsoil is characterised by the "Layers of Theologos", four tectonic frequencies which consist of a palaeogenous flysch, compact green slates, marbles, sedimentary formations containing lignite etc. The island's climate is dry and cool and allows the cultivation of wheat, barley, and citrus trees. Its 450 inhabitants are employed in growing onions and tomatoes as well as in the oil industry and viniculture. Anafi is full of thyme which produces fine honey. Stock-breeding is quite developed and the "vrasta" cheeses of the island are celebrated for their softness. The locals enjoy the beauty of their island and try to serve visitors as best they can. They are simple, open-minded people who do not fight progress as long as it does not corrupt their special character.
