On the way to Cape Sounio, you will discover Vouliagmeni Lake. It is a rare and very interesting geological formation, a lake of brackish waters surrounded by rocks, like a volcanic crater filled with green-blue water, a real treasure of nature. The lake has a rich aquatic life and is continuously replenished from the sea and underground thermal springs, creating a natural thermal spa.

You can bath in its therapeutic waters (even in winter time), and experience the unique sensation of little fish (not piranhas!) taking care of your skin in an idyllic environment!
