Being part of a secret underground river in the past, today the multi-dimensional cave has 13 cascading lakes of varying sizes, a very unique feature as far as caves go. Only about 500 meters are open to visitors because of the rough terrain. By the end of winter, when ice melts, it floods the cave and creates a series of streams and waterfalls.
Human and animal fossils were discovered in the lower level, including that of a hippopotamus, creating an laboratory-like haven for scientists. There are ancient myths connected to the caves as well, where the daughters of King Proitos arrogantly bragged that their beauty surpassed the Goddess Hera. Because of their vanity Hera cursed their sanity, where they thought themselves wild animals dashing across the fields of the Peloponnese. Eventually Melambodas found them in these caves and cured them.
