What it is

Europe’s prescribed cure, still paid for by health insurers

Roman, revived across the Habsburg and German spa towns from the eighteenth century.

The European thermal cure is the oldest continuously practised form of medical tourism there is, and the least understood outside the continent. In Germany, Austria, the Czech Republic, Hungary, France and Italy a *Kur* is a prescribed course — a physician examines you, writes a programme of bathing, drinking, inhalation and rest over two to three weeks, and in several of these countries some portion of it is reimbursed by the health system. That reimbursement is the most useful signal available about how the practice is regarded where it is actually practised.

What distinguishes it from a spa is the word "course". A single thermal bath is a pleasant afternoon. Balneotherapy is a defined number of exposures over a defined period, at a defined mineral composition and temperature, and the effect it claims is cumulative. Taking one and expecting the benefit is like taking one physiotherapy appointment.

The drinking cure — *Trinkkur* — is the half foreigners skip and Central Europeans consider the point. At Karlovy Vary you walk the colonnades with a porcelain cup and a spout, drinking specified springs at specified temperatures before specified meals, on a doctor’s schedule. It looks like a promenade. It is a prescription.

The hard facts

  • Eleven towns across seven countries were inscribed together as "The Great Spa Towns of Europe" on the UNESCO World Heritage List in July 2021, including Baden-Baden, Karlovy Vary, Bad Ems, Spa, Vichy, Montecatini and Bath.
  • The Friedrichsbad at Baden-Baden opened in 1877 and still runs its Roman-Irish bathing circuit.
  • Karlovy Vary’s Vřídlo (Sprudel) spring erupts at around 72 °C; the town’s springs are drunk at graded temperatures rather than at source heat.
  • Bad Gastein’s thermal water emerges at around 45.8 °C and the valley’s therapeutic use of its mine tunnels dates to the mid-twentieth century.
  • In Germany and Austria a Kur is a physician-prescribed course, and elements are reimbursable under some statutory health insurance conditions.
  • The term "spa" itself derives from the town of Spa in Belgium.

We would talk you out of it

Bad Gastein. Gastein is a genuine two-season alpine resort. Deep winter pairs the thermal baths with the Ski amadé area; high summer opens the Hohe Tauern hiking that the doctors prescribe as the other half of the cure. April to May and November are the classic Alpine Zwischensaison, when half the valley closes.

What we would tell you on the phone. Genuinely medical in the German-speaking world. A Kur is prescribed by a doctor, delivered under medical supervision at an accredited Kurhaus, and part-reimbursed by statutory health insurance in Germany, Austria and the Czech Republic. The water itself is analysed and certified for mineral content.

Asked and answered

Questions we actually get

Do I need a doctor’s prescription?
For the medical version, yes — and the examination happens on arrival at the cure centre. For the towns, the bath houses and the colonnades, no: you can buy a ticket and walk in, and a great many visitors do exactly that.
Three weeks is a long time. Does a week do anything?
A week is a pleasant week. The claimed effect of balneotherapy is cumulative and the trials that show benefit run courses of two to three weeks. We will book you a week and tell you honestly that you are buying the town rather than the cure.
Is the textile-free bathing negotiable?
At the historic Roman-Irish houses, no — the Friedrichsbad circuit is textile-free throughout, with some days mixed and some separated. The modern thermal complexes next door are swimwear. Both exist in the same towns precisely because both preferences do.
What about radon at Bad Gastein?
It is licensed in Austria, partly reimbursed, and genuinely contested — radon is a known carcinogen and the low-dose hormesis argument is not accepted outside the field. It is contraindicated in pregnancy, in active malignancy and in several cardiac conditions. If you are considering it, read the argument on both sides; we will not sell it as uncomplicated.
Radon. Should I be worried?
It is a fair question and the honest answer depends on your risk tolerance. The exposure is measured, capped and medically supervised, and there is a reasonable older evidence base for symptomatic relief in ankylosing spondylitis — but the best-designed recent trial, RAD-ON02, did not confirm the effect. It is still ionising radiation. If that sits badly, take the thermal and walking course instead; it stands on its own.
Is the winter or the summer course better?
For the galleries it makes no difference — they are inside a mountain at a constant temperature. For everything else, summer, because the graded walking is prescribed and the Hohe Tauern paths are open.
