Locals call it a “hidden gem,” and honestly, it lives up to that name. It’s set just beyond the city’s noise.
I couldn’t believe how quiet and relaxed the lake felt, considering how close it is to Athens. Sunbathers stretched out on the shore, and swimmers glided through the warm, clear water.
Legend says the lake is bottomless, and nobody has mapped all its underwater caves yet.

Thermal water constantly flows up from deep underground, keeping the lake clean and clear. The mix of salty seawater and hot groundwater earns Vouliagmeni its “thermal paradise” nickname.
