Vouliagmeni Lake | Athens
Updated: Dec 5, 2019
Lake Vouliagmeni is a small lake adjacent to the Mountain Hymettus fed by underground warm currents, declared as a Natural Monument.
The lake was created around 2.000 years ago from the collapse of the ceiling of a cave after an earthquake. Its unique characteristics are: a) it has warm seawater (always at 21-24 °C) and rich content of hydrogen sulphide, which made it function as a natural spa since the 19th century, b) it hosts a unique species of sea anemone, c) it has a very complex underwater cave system which has never been totally explored due to its dangerous complexity.
