Thermes Marins Bali: The Aquatonic Seawater Pool at AYANA Jimbaran

On the Jimbaran cliffs, Thermes Marins Bali at AYANA Resort Bali holds something rare in Southeast Asia: the Aquatonic Seawater Therapy Pool, a warm seawater pool fed directly from the Indian Ocean. This is not an ordinary swimming pool but a therapy circuit you walk through slowly.

What Is Thalassotherapy?

Thalassotherapy uses warm seawater as the therapeutic medium. Marine minerals such as magnesium and potassium are absorbed through the skin, while the water’s buoyancy takes the load off your joints. What you notice most:

• Muscles stiff after a long flight or a full day of surfing loosen up
• Circulation improves and swollen legs settle down
• Neck and shoulder tension from long hours of sitting eases

The 12-Station Jet Circuit

The pool has 12 hydromassage stations with over 60 jet streams, geysers and micro-bubbles. Follow them in order rather than jumping around:

• Neck and shoulders: stand with your back to the jet and let it work the trapezius for 2–3 minutes
• Back and lower back: lean in; the jet pressure is strongest here
• Legs and feet: the floor geysers get the circulation moving
• Current channel: finish by walking against the circular current

A full lap takes about an hour; session packages usually allow up to two hours.

Access, Prices & What to Bring

• Open to non-staying guests, not just resort guests — book a pool session or a spa package
