Greek medicinal baths

The Methana Peninsula is famous not only for its fascinating volcanic landscape but also for its unique thermal springs, which are among the most remarkable in all of Greece. They originate from the region’s ongoing volcanic activity, where an underground magma dome—located 4 to 7 kilometres deep—heats the groundwater that rises through fissures to the surface, emerging as soothing, mineral-rich healing water.

Origin and History

The ancient travel writer Pausanias already mentioned, in the 2nd century AD, hot springs that appeared after the volcanic eruption of 230 BC. These springs were later used for healing purposes, probably already during the Roman period, when bathhouses and water-collecting basins were constructed.

Modern use began in the 19th century: around 1870, the first simple bathing facilities were built, and by 1906 the organised spa operation began. The representative bathhouse still standing by the harbour was designed in 1917 by the renowned architect Ernst Ziller. With its neoclassical façade and elegant symmetry, it remains one of Greece’s most beautiful historic spa buildings.

In the 1960s, Methana became the second-most important spa town in Greece, after Loutraki, attracting tens of thousands of visitors seeking relief from rheumatism, skin conditions, and joint ailments.

The Springs Today

Many of the thermal springs are still active. Some flow directly into the sea, forming natural “marine spas”, while others bubble up in small rock basins. The water temperature ranges between 28 °C and 41 °C depending on the source.

There are two main types of springs:

• Sulphur springs, typical around the harbour of Methana, beneficial for skin and joint conditions.
• Chloride-sodium springs, near the coast, helpful for rheumatic and gynaecological issues.

Most notable springs:

Sfagia Spring – near the village entrance, freely accessible, with turquoise water and a characteristic sulphur aroma.

Agios Nikolaos Spring – close to St. Nicholas Chapel, reaching up to 42 °C; home to the modern Methana Volcanic Spa.

Pausanias Baths – on the northern coast, where hot water meets the sea, creating natural warm pools used by locals.

Healing Power from the Depths

The water contains sodium, potassium, chloride, bromide, and sulphur compounds such as H₂S, which provide its healing properties. Traditionally, Methana’s thermal waters are used to treat:

• Rheumatism and arthritis
• Spinal and disc disorders
• Skin conditions (e.g. psoriasis, eczema)
• Respiratory and gynaecological problems

Here, healing and nature come together – the sea breeze, the scent of sulphur, and the quiet pulse of the volcano that still breathes beneath Methana.
