About Kaiafas Springs Hydrotherapy Center
Kaiafas Springs Hydrotherapy Center, Greece is a paid seasonal thermal facility near Zacharo in the southern Ilia region of the Peloponnese, approximately 30 kilometres south-east of Pyrgos and 20 kilometres south of Ancient Olympia. The site is part of the Natura 2000 network of protected areas and lies within a landscape combining pine and eucalyptus forest, Kaiafas Lake, and the Ionian Sea beach at Zacharo nearby. The springs have been documented for their therapeutic properties since antiquity.
The spring water emerges from the Cave of the Anigrides Nymphs in the cliffs of Mount Lapithas. The water is hypothermal, moderately sulphuric, sodium chloride, and hypertonic, flowing at 31 to 34 degrees Celsius. The hydrotherapy centre includes an outdoor pool with a retractable roof and 14 individual treatment tubs. A separate spring, the Geras or Geranio spring, provides mineral water suitable for internal use. Accommodation is available at the on-site Hotel Olympia, set on a small island in the lake.
For visitors researching therma loutra in the Peloponnese, Kaiafas is the most distinctive regional site due to its cave setting, lake environment, and protected natural ecosystem. The centre has operated since 1907 and has been managed by the Hellenic Public Properties Company since 2000.

Suitability & Accessibility
Who Kaiafas Springs Hydrotherapy Center Suits
Kaiafas Springs Hydrotherapy Center suits visitors seeking a managed therma loutra experience in a natural protected-area setting, particularly those with chronic rheumatic conditions, arthritis, myositis, neuralgia, dermatological conditions, and atypical gynaecological conditions. The water temperature of 31 to 34 degrees Celsius is relatively mild, making it accessible to visitors who find higher-temperature springs difficult to tolerate.
The outdoor pool, individual tubs, and cave-adjacent setting make this site appealing to both short recreational visitors and those undertaking multi-day therapeutic programmes. The adjacent Hotel Olympia and the nearby Ionian Sea beach make a stay of several days practical. The moderate water temperature and cave environment also attract visitors interested in the mythology of the site, as the caves are documented as nymph dwellings in ancient texts including Strabo.
No formal wheelchair accessibility documentation was found for this site. The terrain includes lakeside and forest paths, and the cave entrance may present challenges for guests with mobility limitations. Visitors with specific mobility needs are advised to contact the hydrotherapy centre directly. Reduced-rate admissions are available for guests with disabilities, persons over 70, large families, and unemployed individuals. The site operates seasonally from May to November.
Safety & Etiquette
Kaiafas Springs Hydrotherapy Center Safety Tips
Kaiafas Springs Hydrotherapy Center is generally safe for most visitors, as the water temperature of 31 to 34 degrees Celsius is lower than many other Greek thermal sites. However, the water is moderately sulphuric and hypertonic, and guests with cardiovascular conditions, high or low blood pressure, or pregnancy should consult a physician before bathing. The hydrogen sulphide content gives the water a characteristic odour, which is normal for this spring type and is part of its therapeutic character.
The cave of the Anigrides Nymphs creates a natural steam bath effect in its interior sections, where temperatures and humidity are higher than in the open pool area. Visitors should allow their bodies time to acclimatise when approaching or entering the cave zone. Extended time in the higher-humidity cave sections may be more demanding than bathing in the open outdoor pool.
The site operates within a Natura 2000 protected area, meaning the natural environment is ecologically sensitive. Visitors are asked not to disturb vegetation, the lake ecosystem, or the cave rock formations. Swimming in the lake is separate from the hydrotherapy centre and is not part of the therapeutic offering. The Geras spring water available for drinking should only be consumed in the quantities recommended on site, as mineral spring water taken internally in large amounts can affect the kidneys. The hydrotherapy centre operates from May 15 to November 15; confirm current hours before travelling.
