This is a tour organized only for ISIT 2024 participants. Depart with a private guide and bus to Lake Vouliagmeni. Immerse yourself in its pristine waters and bask in the soothing embrace of thermal springs, or just relax at the cafeteria. The lagoon formed about 2,000 years ago, following an earthquake. The lake has quite unique environmental conditions: it is supplied with warm seawater (28-35°C) via an underground channel spreading through a network of flooded caves, so its temperature never drops below 18°C. In July, the water temperature ranges between 23.7 – 27.8 °C. Because of its constant warm water temperature and its rich content in hydrogen sulfide, the lake functions as a spa since the end of the 19th century. The lake hosts the only existing population of a species of sea anemone, “Paranemonia vouliagmeniensis”. It has been declared a natural monument by the Greek State and is part of a Natura 2000.

After Lake Vouliagmeni, you will head to Cape Sounion, by driving along the coastal road of the Athenian Riviera with spectacular views of the Saronic Gulf. Upon arrival, you will visit the Temple of Poseidon, founded in the fifth century B.C. and built on a 60-meter-high promontory surrounded by the sea. You will enjoy impressive views of the Aegean Sea from the ruins, having time to relax and take photos before the sun settles at around 20.45.
