Ax-les-Thermes sits on some of the hottest thermal waters in the Pyrenees, naturally reaching 72–77°C, rich in sulfur and mineral content. People have come here for treatment and rest since at least the medieval period, and the town’s two thermal sites — Les Thermes du Modèle and Les Thermes du Teich — still shape daily life in the town center today.

There are two very different ways to experience the baths, and it’s worth knowing the difference before you book.

The Traditional Cure: 18 Days, Medically Prescribed

This is the classic French "cure thermale" — a medically prescribed, 18-day treatment programme, partially reimbursed by French health insurance (Assurance Maladie), aimed at chronic conditions in two areas the station is accredited for: rheumatology and respiratory ailments.

  • Requires a doctor’s prescription

  • Runs 18 consecutive days, with daily treatments

  • Partially reimbursed (around 65% for a standard cure, up to 100% for long-term conditions)

  • Booked directly through the thermal establishment, not through general accommodation sites

This is a serious, structured stay — most curistes settle into a rental or residence for the full three weeks. If this is your situation, look for accommodation with a proper kitchen and laundry, since you’ll be living here, not just visiting.

Short Wellness Cures: 3 to 6 Days, No Prescription Needed

Alongside the traditional cure, the baths now offer shorter wellness programmes that don’t require a prescription — a more recent addition aimed at visitors who want the benefits of the thermal waters without committing to a full medical cure:

  • Aqua détox — purification and detox-focused treatments

  • Aqua boost — vitality and energy-focused treatments

  • Aqua respire — breathing and respiratory well-being

These run over a long weekend or a short midweek break, with several treatments a day, and are booked directly with the thermal establishment. This is the better fit for most visitors — a genuine wellness break rather than a medical programme, and it pairs naturally with a few days of exploring the town, hiking, or (in winter) skiing nearby.

Planning Your Visit

  • The thermal baths open in early January each year; exact dates and off-season closures vary between the two sites, so it’s worth checking directly with the establishment before you travel

  • Book treatments in advance during busy periods — availability at the reception desk can be limited on short notice

  • Children from age 3 can be treated for certain conditions (asthma, ear infections) when accompanied by an adult

Where to Stay

Studio Natik is a short walk from both thermal sites in the town center — no need to drive for your daily treatments. A full kitchen and washing machine make it practical whether you’re here for a long weekend or a longer stay.
