Vouliagmeni Lake

The hidden treasure of Attica’s nature is Lake Vouliagmeni, located in the middle of the Athenian Riviera. This remarkable geological feature is waiting to be uncovered in a lovely landscape. The Lake’s brackish water, which is fed both by underground thermal springs and the sea, provides a natural and unique thermal spa experience.

The majestic rock, warm waters, complex underwater passages, and lush flora combine to create a geological marvel unlike any other. The cave’s roof collapsed due to erosion induced by the high temperature of the flowing water, and the lake gained its current shape. The lake is on the National NATURA 2000 list and is designated as a Site of Outstanding Natural Beauty by the Ministry of Culture.
