Vouliagmeni Lake is a natural wonder on the Athens Riviera, just 25 kilometers south of the city center. Tucked beneath limestone cliffs and lush greenery, it offers a peaceful escape from urban life. The lake formed thousands of years ago when part of a cave roof collapsed. Warm spring water filled the space, mixing with the sea. This is why its name means “sunken lake” in Greek. 

The lake’s waters stay warm all year, ranging from 22°C to 29°C. Underground thermal springs feed it constantly. Seawater also flows in through an underwater tunnel. This unique mix creates slightly salty, mineral-rich water. Many visitors come for its healing properties. The water contains magnesium, potassium, calcium, and other beneficial minerals. 

The facilities are clean and well organized. Visitors will find sunbeds, umbrellas, a changing area, and freshwater showers. The lake is deep in the center but shallow near the edges, making it suitable for all ages. 

Moreover, the lake is famous for being a habitat of the tiny “doctor fish” called Garra rufa. These fish gently nibble dead skin, giving a natural pedicure. It tickles at first, but most people find it soothing. The experience is unique and completely safe. There’s also a café and restaurant on site. 

Lake Vouliagmeni is open year-round. During summer, it gets busy, so visitors should arrive early to find a good spot. Parking is available nearby. The beach is also reachable by taxi or bus from Athens. Entry comes with a fee, but the clean facilities and beautiful setting make it worthwhile. 

What’s more, Vouliagmeni Lake is part of the Natura 2000 protected network. Authorities take care to preserve its unique ecosystem. You’ll see birds, plants, and fish that thrive in this special environment. 

If you’re in Athens and want a break from sightseeing, this is the perfect getaway. The lake combines nature, wellness, and calm—all just a short ride from the city.
