One of the world’s most beautiful and unique karst systems is on the southern outskirts of Hymettus, a few meters from the Eastern shores of the Gulf of Vouliagmeni.
The lake of Vouliagmeni is an elaborate geological phenomenon separated from the clear blue waters of the Saronic by a narrow strip of limestone rocks.
With the total number of routes explored to date amounting to 4.2 km at a penetration length of 933 meters from the cave entrance and with a depth now reaching 130 meters, the main chamber is considered the largest flooded chamber in Europe with a volume that reaches 2,000,000 m3.
Our team Top2Bottom Diving Team in collaboration with the Addicted2h2o on 24/07/2022 penetrated the first chamber of the cave, which reaches a maximum depth of 70m and a minimum ceiling height of 15m.
