The Olympoi cave is at an altitude of 110 metres above the sea. It is an underground cavern with 52 meters depth.

Due to its numerous calcite formations (stalactites and stalagmites), this cave of Chios can be ranged amongst the most remarkable and beautiful caves of Greece. The cave formations are still developing.

The relative humidity of the cave is up to 95% while its temperature is stable around to 18°C. The double doors system at the entrance of the cave aims to keep conditions stable in it, in order for the cave micro-climate to remain unaffected.

The cave was inaccessible for centuries, until members of the Hellenic Speleological Society explored it. The rich décor of the cave triggered the speleologists’ imagination giving the formations names such as: Medusa, Armonio, Cave People.

The largest part of the cave is accessible to visitors, accompanied by a guide.

Excavations' evidence has confirmed that the cave was inhabited in the middle Neolithic ages (6.500 – 5.500 B.C.). The findings include tools, ceramics and weapons and they are exhibited at the Chios Archaeological Museum. At the entrance of the smaller top cave the temple of Panagia Agiogalousaina (13th century) was built.
