We find the world renowned cave ‘of Hermes’ in Ziria, at the east side of the mountain. According to mythology, this is where the god Hermes was born, and it is even claimed that this is where he hid the immortal cows he had stolen from his brother Apollo.
According to Pausanias, there was also a Temple dedicated to Hermes in the area. At the foot of Aepytus hill we find the ruins of a large building structure which is most probably part of the ancient temple Pausanias was referring to.
The cave was explored and mapped in 1971 by a Task force of the Speleological Service. It is located at an altitude of 1.700m. It is one of the few Greek caves located at such a high altitude and it stretches 1.200m2 and has 8 chambers decorated with stalactites and stalagmites. It has a rare kind of white lithomatic decoration, called spilaiogala (milk of the cave).
