Aspronisi

Aspronisi, the "white island", is an uninhabitated island in the Santorini archipelago and, like Thira and Thirassia, form spart of the volcano’s caldera.

It is in private ownership and – at least theoretically – on sale. It is not sure whether the island without water and vegetation could be used in a reasonable way. The rock around it is precipitous and up to 70 m high so that the island cannot even be easily accessed from the boat. At least, Aspronisi’s surroundings are said to be an ideal diving area.
