The cave was above water during the last ice age, when sea level was more than a hundred metres lower and Crete's dwarf elephants sheltered in it. It flooded as the sea rose. A local diver found it in 1999 and Greek palaeontologists have worked it since, which is why access is controlled. Anchorage: Anchor off the Drepano headland in settled weather; Souda and Chania are the harbours. Hazards: A true overhead environment with a silt floor and fossil material that must not be touched. Guided cave-trained dives only. Altro
