Pictures magic, peculiar creations of nature, creatures strange and exotic… the underground kingdom of Chios calls you to explore it. Live the adventure and the experience, feel the intensity… Gain the knowledge! Stalactites, stalagmites, ecentrites. White, red, yellow. Work of art of thousands of years inspired creation. Pictures and sentiments unusual… filled with awe! Enjoy all these with the safety that provides a visit in a tourist-developed cave. And if caving is your passion, live the emotion that offers the exploration of caves in their natural form, without human interventions. Chios is the ideal place for holidays for the friends of caves. Chios easily can be characterized as geological paradise since you can find here the most ancient rocks of all Europe; the most ancient rocks of Greece, Ammoniton, impressive cracks and a big number of karstikon shapes. In Chios three caves are the most distinguished, not of their size, but of their exceptional beauty and interest: the Cave of Olympi, the Cave of Lithi and the Cave of Agio Galas.
