Vouliagmeni Lake
Attikí
Lake Vouliagmeni is a natural brackish lake located at the southern edge of Mount Hymettus near Vouliagmeni, Athens, Greece. Formed approximately 2,000 years ago by the collapse of a large underground cavern roof, the lake features warm waters ranging from 21 to 29°C supplied by underground seawater currents and a freshwater spring, creating a unique environment with reduced salinity. Its underwater cave system extends deep into the mountain and remains largely unexplored, with several diving expeditions conducted to chart its depths. The lake has been used as a therapeutic spa since the late 19th century, thanks to its constant warm temperature and high hydrogen sulphide content. It hosts the only known population of the sea anemone species Paranemonia vouliagmeniensis and is part of the Natura 2000 protected areas, recognized as a natural monument by the Greek State. Visitors can enjoy swimming, spa facilities, and dining at the onsite restaurant, all set within a landscape of exceptional natural beauty and ecological significance.

Histoire
Lake Vouliagmeni was formed about 2,000 years ago when the roof of a large underground limestone cavern collapsed due to erosion and tectonic activity.
Unlike many ancient Greek landmarks, it is not mentioned in classical texts, likely because it formed after the classical period.
Since the late 19th century, the lake has been used as a natural spa, capitalizing on its warm, mineral-rich waters.
Over the decades, it has gained protection status as a natural monument and part of the Natura 2000 network, preserving its unique ecosystem and geological features.
