Discovered and officially documented in the 1970s, the cave now presents a breathtaking exhibition of Karst formations resulting from the dissolution of soluble carbonate rocks. Not to mention its immense size, Alistrati Cave is well known. It contains chambers and is 3 km long.

Cave Perama, Ioannina

The largest cave in Greece, Perama Cave, is located 5 miles from the picturesque lakeside city of Ioannina in Epirus. It covers an incredible 46 square km. Its passages wind inside the bowls of Goritsa Hill for approximately 1.7 km. The cave has a geological connection to the neighbouring Lake Pamvotida and was formed about 1.5 million years ago. It’s a section of an underground riverbed that was formed when the plain was totally submerged by the lake and Goritsa Hill was an island. The inhabitants of the nearby Perama hamlet sought refuge from aircraft bombardment during World War II, marking the first recorded instance of its existence in the modern era. Locals, however, are usually believed to have been aware of it since approximately 1900.

Petralona Cave is 300 metres above sea level and is located on the western slopes of Mount Katsika, close to Nea Moudania in the Central Macedonian district of Halkidiki. The amazing fossilised skull of the so-called “Archanthropus of Petralona,” a Homo erectus-like hominin (archaic human) thought to be the earliest European at the time of its discovery in 1960, is housed in this well-known cave together with an impressive array of stalactite and stalagmite formations. Petralona Cave was found by chance in 1959 by local shepherd Filippos Hatzaridis. The following year, Greek anthropologist Aris Poulianos began methodical excavations, which increased the cave’s significance. Numerous tools and artefacts from the Palaeolithic (Old Stone Age), along with hundreds of fossilised animal bones from more than 50 species, were discovered during these digs.

Melissani Cave

It is located near Karavomilos on Kefalonia’s island, is a stunning lake cave with turquoise waters. Over 3.5km long, it was discovered in 1951 by speleologist Giannis Petrochilos.

Attica’s Koutouki Cave in Paiania

Located 35 km east of central Athens, nestled within the subterranean network of Mount Ymittos, Paiania Cave is a testament to the extraordinary solubility of limestone in rainwater, which has shaped bizarre rock forms over endless millennia. The stalactites and stalagmites in the cave have created a magnificent tapestry due to this natural process.

When a hapless goat fell through the ceiling in 1926, the location was inadvertently discovered. A few decades later, in 1954, Yannis and Anna Petrochilos of the Hellenic Speleological Society carried out methodical investigation on it. The Koutouki Cave sprang to fame as a popular tourist site due to its enormous rock formations, striking red colours caused by iron oxide, and enormous size (38.5 metres in height and over 350 metres in length).

The Cave of the Lakes

The first excavation of Vlychada Cave, which was located in 1949 by Giannis and Anna Petrocheilou, the founders of the Hellenic Speleological Society, revealed only a small portion of its enormous expanse. Its mysteries have been revealed over the years, and around 15 kilometres of passages have been surveyed and investigated. The attraction of the cave even reaches below the surface, where an underground river eventually meanders.

Dictaean Cave
