The classic three-week cure in Mariánské Lázně — why people come for three weeks
Three weeks is the traditional length of a therapeutic stay in European spa medicine. In Mariánské Lázně (Marienbad), the cure has been prescribed this way since the 19th century, and most stays covered by health insurance still follow the same rhythm today: the Czech indication list assigns 21 or 28 days to comprehensive spa care depending on the diagnosis, and 14 or 21 days to contributory care. Self-paying guests choose the length in consultation with the spa physician; the specialist literature regards two to three weeks with 10–21 treatments as the usual length of spa treatment (Maraver et al., 2020; Karagülle and Karagülle, 2021, Int J Biometeorol).
Marienbad is one of the places where the classic three-week cure is still practised in the form it took two hundred years ago. More than 40 mineral springs of differing chemical composition, natural carbon dioxide from the Maria Spring and peat from the Slavkov Forest form the therapeutic foundation. Add to that an altitude of 630 metres in the midst of forests; since 2023 Marienbad has held the status of a climatic spa, and climate therapy is part of the treatment plans.
What follows is a complete guide to the three-week cure in Marienbad: week by week, with a treatment plan, excursions, costs and practical tips. The specific plan of treatments is drawn up by the spa physician at the initial examination; the schedule below is an example, not a prescription.
What the studies say about the three-week cure
Randomised trials that looked specifically at three-week spa programmes for particular diagnoses show what can realistically be expected from such a cure:
- Knee osteoarthritis. In the French ANGELLO trial with 145 patients aged 50–80, function, pain and quality of life improved after three-week spa treatment, and the difference from usual care was still present at 6 months (Forestier et al., 2025, Int J Biometeorol). In an older multicentre trial with 382 patients, 51% of patients achieved clinically meaningful improvement at 6 months after 18 days at the spa, compared with 36% in the control group; quality of life did not differ (Forestier et al., 2009, Ann Rheum Dis). In a Tunisian trial with 240 patients, pain at 12 months was lower only in the group given three-week spa treatment, not after standard rehabilitation (Fazaa et al., 2014, Ann Phys Rehabil Med). According to a systematic review, the effect in knee osteoarthritis is clinically meaningful for 3–6 months, sometimes up to 9 (Forestier et al., 2016, Ann Phys Rehabil Med).
- Chronic low back pain. Two French randomised trials from the nineties (102 and 121 patients) recorded better spinal mobility, less pain and lower use of painkillers after a three-week cure; the relief and lower medication use persisted for 6–9 months, while functional scores returned to baseline (Guillemin et al., 1994, Br J Rheumatol; Constant et al., 1995, J Rheumatol).
- Ankylosing spondylitis. In a Dutch trial with 120 patients, a three-week spa programme with exercise improved function and quality of life throughout 40 weeks of follow-up (van Tubergen et al., 2002, Arthritis Rheum).
- Overweight and obesity. In a French trial with 257 people, a three-week spa programme with dietary and exercise education led after one year to a fall in BMI of 1.9 points compared with 0.2 under usual care (Hanh et al., 2012, Evid Based Complement Alternat Med).
All of these trials were open-label, that is unblinded, and each concerns a single diagnosis; their results cannot be transferred to other indications. For the other indication groups, the position is that they are treated in Marienbad according to the indication list, and that the length of stay is set by the list and the proposal of the treating doctor.
Week 1 — Arrival and acclimatisation
Day 1 — Arrival and initial medical examination
Plan to arrive in the morning. From Prague it is two and a half hours, from Plzeň an hour and a half. More information in the practical information section.
After checking in at the hotel comes the most important appointment of the whole cure: the initial examination by the spa physician. For a three-week cure this is not a formality but a thorough medical history. The physician records previous illnesses, current complaints, medications and laboratory results and draws up an individual treatment plan for 21 days. Only the physician decides which treatments you will receive and how often.
In the afternoon, a first walk through the spa park to the Colonnade. A light dinner, an early night.
Days 2–3 — First treatments: mineral bath, drinking cure, massage
The start is gentle. In the morning, the drinking cure — on an empty stomach to the Colonnade, fill the spa cup, sip slowly while walking. Which spring, how much and when is decided by the physician according to your diagnosis; traditionally the Cross Spring is prescribed for digestive complaints and the Rudolph Spring for diseases of the kidneys and urinary tract, while the Forest Spring tends to be the choice for beginners. Usually two to three cups a day.
In the late morning the first treatments: a mineral bath in natural healing water (34–36 °C, 20 minutes), followed by a classic massage (back and neck, 30–50 minutes). Mild tiredness after treatments is common in the first days.
In the afternoon, short walks in the spa park or to the Geological Park (3 km). Climate therapy — time in the forest air, the elevated location, guided walks — is part of the cure.
Days 4–5 — CO₂ bath and peat wrap
Now come the Marienbad specialities. The CO₂ bath: in a tub with natural carbon dioxide, fine bubbles form on the skin. The gas penetrates the skin and dilates the cutaneous vessels, increasing blood flow in the skin and subcutaneous tissue — a mechanism described in review papers on CO₂ balneotherapy (Pagourelias et al., 2011, Int J Biometeorol). The physician decides whether the bath is suitable, as it also has contraindications.
The peat wrap: peat from the Slavkov Forest, heated to 42 °C, is applied to the body. Peat releases heat slowly and evenly; the deep warming eases muscle tension. After both treatments, at least an hour of rest.
Day 6 — Rest day and a trip to Kladská
No treatments on the sixth day. Take a trip to Kladská — a nature reserve with a peat bog fifteen minutes from Marienbad. Wooden boardwalks lead through a quiet landscape of birches and mosses. The loop takes an hour. You will find more ideas for excursions on our page.
Day 7 — Expanding the programme
On the seventh day the programme usually expands. Gas injections — natural CO₂ applied with a fine needle under the skin around the joints or spine — are a traditional Marienbad treatment that the spa physician adds as a complement to wraps, baths and physiotherapy. Alongside them, inhalations of Marienbad mineral water. In the afternoon, the ascent of Hamelika, Marienbad's home hill (4 km, 1.5 hours), with a panoramic view.
Week 2 — The full programme
Days 8–10 — When the body is tired
In the second week some guests feel transient fatigue or a temporary worsening of their complaints; spa tradition calls this the spa crisis. It is no cause for alarm, but nor is it something to brush aside: tell the spa physician, who monitors this phase and adjusts the treatment plan if necessary.
The intensity of treatments increases: CO₂ baths three times a week, peat wraps twice, plus electrotherapy, underwater massage and further mineral baths. The drinking cure continues daily.
Day 11 — Teplá Monastery
A rest day. The Premonstratensian monastery of Teplá, founded in 1193, lies twenty minutes to the east. Its baroque library with more than 100,000 volumes is worth the trip in itself. It was the monks of Teplá who, in the 19th century, systematically opened up the healing springs of Marienbad.
Days 12–14 — The most intensive days
The most intensive days of the cure. The morning drinking cure, then two treatments back to back: a CO₂ bath and a peat wrap, or a mineral bath and an underwater massage. In the afternoon, terrain therapy — walks with systematically increasing distance and elevation gain.
At the end of the second week, an interim examination with the spa physician. Blood pressure, mobility, how you feel — everything is documented and the treatment plan is adjusted for the third week.
Week 3 — A settled rhythm and the conclusion
Days 15–17 — An established rhythm
The third week tends to be calmer than the second. The intensity of treatments remains, but the programme has become routine: getting up, the drinking cure, a treatment, rest, a walk. Many guests say that it is in this week that they settle into the slower pace of the day.
Treatments: CO₂ baths, peat wraps and mineral baths in the established rhythm. The drinking cure remains a fixed part of the morning.
Use the afternoons for longer hikes in the Slavkov Forest. Terrain therapy reaches its full extent — routes of 8–10 km with gentle elevation gain, if the physician approves them.
Day 18 — Loket Castle
The last excursion. Just under an hour to the north-east, the medieval castle of Loket rises above a meander of the River Ohře. Goethe called the little town "the most beautiful in Bohemia". On the way back, a stop in Bečov nad Teplou — the reliquary of St Maurus, a Romanesque goldsmith's masterpiece of world importance.
Days 19–20 — Final treatments and the Roman Baths
The last days of treatments. A final CO₂ bath, the last peat wrap, a full-body massage. The spa physician carries out the final examination, compares the values with those at admission and prepares the spa report with recommendations — diet, exercise, any follow-up treatments at home.
The highlight: the Roman Baths at Ensana Nové Lázně. A bathing hall with original mosaics from 1896, marble columns, a warm and a cold pool. King Edward VII bathed here. Booking information on our accommodation page.
Day 21 — Farewell
The last morning: take the spa cup, a last glass at the Colonnade, a last walk through the park. The routine that has become second nature over three weeks — getting up, the drinking cure, movement, a treatment, rest — take it home with you as an attitude.

How much does a three-week cure cost?
Marienbad is considerably cheaper than comparable spa resorts in Germany or Austria. A realistic budget for 21 days for a self-paying guest:
Accommodation (21 nights): A mid-range hotel in the centre from around CZK 30,000–38,000 in a double room. An Ensana hotel with its own spa facilities and half board from around CZK 45,000–62,000. More on our accommodation page.
Treatments: For 45–55 treatments, allow CZK 15,000–25,000. Individual prices: CO₂ bath from CZK 750, mineral bath from CZK 620, peat wrap from CZK 750, massage (50 min) from CZK 1,100, gas injections from CZK 500, inhalation from CZK 370, Roman Baths from CZK 870.
Meals: With half board at the hotel, approximately CZK 10,000–15,000 for lunches, drinks and restaurants.
Spa fee and other costs: Approximately CZK 1,200–2,500 for three weeks.
Total budget per person (21 nights): CZK 56,000–103,000, depending on the hotel category and the range of treatments.
Ensana spa packages: The Ensana hotels offer complete 21-day packages with medical supervision, a treatment plan, accommodation and full board — often 20–30% cheaper than booking separately.
Stays covered by insurance: For guests insured in the Czech Republic, a three-week stay can be comprehensive or contributory spa care if the diagnosis matches an item on the indication list. The procedure is described in the guide to the spa treatment voucher.
Who is the three-week cure for
Indications according to the indication list
Mariánské Lázně is a spa resort listed in the Czech indication list for the following groups of diseases:
- Disorders of the locomotive system (osteoarthritis, chronic back pain, inflammatory rheumatic diseases, conditions after orthopaedic surgery)
- Illnesses of the circulatory system (hypertension, ischaemic heart disease, peripheral vascular disease)
- Diseases of the respiratory system (chronic bronchitis, asthma, conditions after lung surgery)
- Diseases of the urinary tract (kidney stones, chronic inflammations, conditions after surgery)
- Digestive system illnesses and metabolic disorders (including diabetes and obesity)
- Oncological diseases after completion of treatment
- Nervous system diseases and skin diseases
For each item the list sets the type of care and the length of stay; for most basic stays in comprehensive care this is 21 or 28 days.
Self-paying guests: regeneration and prevention
Without a medical referral, many guests come for a three-week stay as self-paying guests — after a demanding period, because of long-term stress, or simply because they want to devote three weeks to themselves. For this group there is evidence of an effect on stress: in a Lithuanian randomised trial with 243 adults with high stress levels, even an 11-day spa programme reduced stress, anxiety and fatigue and improved sleep, with an effect lasting 6 months (Rapolienė et al., 2026, BMC Complement Med Ther). A spa stay does not, however, replace psychotherapy or psychiatric care; for long-term anxiety, depression or burnout it complements treatment led by a psychologist or psychiatrist. Preventive and regenerative stays are not covered by insurance.
A repeat stay is expressly provided for under a number of items on the indication list; whether and when to return is recommended by the spa physician in the final report.
What to pack for three weeks
- Comfortable clothing and footwear for walks and hikes
- Sturdy footwear for longer terrain routes
- Swimwear for the pool, mineral baths and the Roman Baths
- Bathrobes are provided by the hotels
- A water bottle and a spa cup (or buy one locally)
- Smart clothing for dinners in the restaurant
- A few books — three weeks is a lot of reading time
- A raincoat — the Slavkov Forest has weather of its own
- Laundry planning: hotels offer a laundry service, or pack for ten days and wash once
- A list of medications and medical records for the spa physician
Booking tips
Best time to visit: May to June and September to October. Milder weather, fewer guests. Winter has a charm of its own — snow-covered spa houses and hot mineral baths at the lowest prices of the year.
Book early: Three-week cures occupy hotels for longer periods. In high season, book three to six months ahead.
Medical preparation: Bring up-to-date medical reports — the spa physician can tailor the treatment plan better when they know your history.
Getting there: A car gives you flexibility for excursions. Alternatively, there are coach connections from Prague or Plzeň. Details in the practical information section.
Twenty-one days in Marienbad is not a holiday in the usual sense. It is time devoted to your own health, in a rhythm that has held here for two centuries. What you take home depends on your diagnosis: for osteoarthritis and chronic back pain, the studies suggest relief lasts 3 to 6 months, sometimes up to 9. And the routine of the morning walk to the Colonnade you can take home whatever your diagnosis.
