Lake Vouliagmeni

Overview

Lake Vouliagmeni is a stunning natural thermal lake fed by underground hot springs, with year-round warm water (22–29°C) in a surreal mineral-rich landscape of collapsed cave formations along the Athens Riviera.

Highlights

• Thermal Waters: Naturally heated mineral-rich water believed to have therapeutic properties.
• Dramatic Setting: The lake occupies a collapsed cave system surrounded by limestone cliffs.
• Year-Round Swimming: Comfortable water temperatures even in winter.

History

The lake formed when the roof of a large coastal cave collapsed thousands of years ago. The underwater cave system extends deep into the hillside and has attracted divers, though the caves are now closed due to fatalities.

Visitor Tips

• Sunbeds Included: Entry fee includes sunbed and umbrella.
• Fish Spa: Tiny Garra rufa fish in the lake nibble at your feet — a natural exfoliation.
• Duration: 2–3 hours.
