The Cave of Drakos in Astypalea Greece, Dodecanese: A lovely natural attraction in Astypalea is the Cave of Drakos, whose name actually means the cave of the dragon. Located close to the fishing village of Vathi, on the northern side of Astypalea, this spot is nice as a trekking destination.
The cave is decorated with impressive stalactites and stalagmites of different colours which they have been formed over time when water, containing lime, runs off the roof. Depending on the mineral contents contained in the water, the stalactites take different colours. Drakos Cave was associated with marauding pirates as it was thought to be a place where the pirates were hiding their treasures. The cave can also be accessed by boat from Vathy.
