About the place

The lake that never gets cold.

Vouliagmeni is a small saltwater lake — about 150 metres long, 50 metres wide — fed from below by a geothermal spring that holds the water temperature at 22–25°C all year, even in February.

The lake sits at the base of a limestone cliff just south of the headland of the same name; it is connected to the open sea by an underwater tunnel cut by the spring, but its surface is sheltered, glass-still, almost always. The water is famously high in salt and minerals; from the 1900s it was a therapeutic spa, and the spa is still working today — a paid entry (€18 day-pass), wooden boardwalks and sun loungers around the perimeter, a small café, the now-famous Garra rufa fish that nibble dead skin off your feet for free. It is not a beach in any normal sense; it is a long slow float in transparent saline water, with the cliff above and the ducks at the edge. Open year-round; busiest in winter and shoulder-season; best at 09:00 in summer before the day gets warm. The divers working the lake bottom are mapping a 100-metre-deep underwater cave system that opens beyond the visible floor — extends inland under the limestone, still being explored.

01Year-round float — 22–25°C water summer and winter; the lake is open and operational on December afternoons. The most surreal Athenian winter outing.
02The fish — Garra rufa — small toothless fish that nibble dead skin off feet. They are everywhere in the shallow ends of the lake; sit on the steps and they come to you. Weird, ticklish, oddly pleasant.
03The cliff — The 30-metre limestone cliff above the lake creates the microclimate — afternoon shade, no wind, a closed acoustic. The whole site feels like an interior room.
04Underwater cave — The lake's cave system extends about 100 metres deep and several hundred metres inland under the limestone — being mapped by a Greek divers' team. Not open to public diving; visible only as the glow of their lights at the bottom on quieter days.
