If you’ve already ruled out Karlovy Vary — say, digestive treatment isn’t what you need, or you simply want a quieter resort — the next decision usually comes down to Mariánské Lázně or Františkovy Lázně. Both are smaller and calmer than Karlovy Vary, both sit surrounded by greenery, and at first glance they can seem similar. In practice, these are once again two different medical directions with different atmospheres.
I live in Karlovy Vary and visit both towns regularly. Here’s an honest comparison: what each treats, what the atmosphere feels like, and who each resort actually suits.
As with any comparison of Czech spa towns, this determines everything else.
Mariánské Lázně specialises in treating kidney and urinary tract conditions — historically the resort’s core focus. Patients come here for kidney stones, chronic urinary tract inflammation, prostate issues, and post-kidney-surgery recovery. The resort describes itself as genuinely unique in the Czech Republic in this regard. Beyond that, it successfully treats metabolic disorders (diabetes, gout), musculoskeletal conditions (arthritis, spinal issues, post-orthopaedic-surgery recovery), and respiratory conditions — using a specific mineral-water inhalation therapy for asthma, bronchitis, and allergic reactions. In recent years, Mariánské Lázně has also become a centre for treating Long Covid symptoms, since breathing difficulties, insomnia, and joint pain align closely with the resort’s strengths.
One important detail: gynaecology is not part of Mariánské Lázně’s core profile. A complete gynaecological treatment programme is currently offered by only one hotel sanatorium there — Centrální Lázně. If you specifically need a gynaecological programme, Františkovy Lázně is the better choice.
Františkovy Lázně takes the opposite approach entirely. Its main specialisation since founding has been gynaecological conditions and infertility treatment. The key natural resource is sulphur-and-iron-rich peat, applied as wraps, baths, or vaginal applications, which improves blood circulation in the pelvic area. Beyond gynaecology, the resort also successfully treats cardiovascular disease, musculoskeletal disorders, and chronic skin conditions.
Practical takeaway: kidney stones, prostate issues, kidney problems, diabetes, asthma, Long Covid symptoms — Mariánské Lázně. Gynaecology, infertility, skin conditions — Františkovy Lázně. Once again, the specific diagnosis decides, not personal preference.
Here the two resorts sit closer to each other than either does to Karlovy Vary — but differences remain.
Mariánské Lázně is the Czech Republic’s second-largest balneological resort after Karlovy Vary, with a population of around 14,000. The town is known for its expansive parks, tree-lined avenues, and magnificent architecture — arguably the most elegant of the three spa towns. The Maxim Gorky Colonnade, at 180 metres, is the longest spa colonnade in the Czech Republic. The surrounding area is remarkably rich in springs: roughly 100 in the wider vicinity, around 40 within the town itself, six of which are used for treatment. The atmosphere is calm but far from small — this is a full-scale spa town with comprehensive infrastructure for both treatment and leisure.
Františkovy Lázně, with around 5,500 residents, is the most compact of the three resorts. The architecture is neoclassical, set within roughly 250 hectares of parkland. This is the resort of maximum stillness and the slowest pace — even compared to the already-calm Mariánské Lázně, Františkovy Lázně feels smaller and more intimate.
Practical takeaway: if you want impressive parks, a larger town, and developed infrastructure while keeping a calm atmosphere — Mariánské Lázně. If you need a maximally quiet, compact place with no urban bustle whatsoever — Františkovy Lázně.
Mariánské Lázně is younger than both of its neighbours — its history as a resort spans roughly 200 years. The healing properties of the springs were known for a long time, but the inaccessible, swampy valley delayed any permanent settlement. The decisive push came from Abbot Karl Kaspar Reitenberger of the nearby Teplá Monastery, who in 1813 built a permanent bathhouse at the sulphurous “Stinking Spring” (now Mariánský pramen) and commissioned landscape architect Václav Skalník to transform the swamps into magnificent parks. Within 100 years, Mariánské Lázně had become one of the world’s most famous spas, hosting guests such as Goethe (who stayed in 1823) and later Richard Wagner.
Františkovy Lázně was officially founded in 1793 by Emperor Franz I, although records of the healing waters date back to 1502 — so formally the springs were known for longer, though Mariánské Lázně received its resort status slightly later than Františkovy Lázně.
Both resorts, together with Karlovy Vary, form the “West Bohemian Spa Triangle” and belong to the international “Royal Spas of Europe” association — a historical recognition of their place in the European spa tradition.
The resorts sit close together, which makes combining them straightforward.
Mariánské Lázně to Františkovy Lázně is about 37 kilometres. Mariánské Lázně to Karlovy Vary is roughly 43–48 km. All three resorts form a compact triangle in western Bohemia, and travelling between them takes no more than an hour by car or bus.
From Prague, both Mariánské Lázně and Františkovy Lázně are roughly 180 km away. Logistically, it makes the most sense to start a trip in Karlovy Vary and move on to the two smaller resorts from there.
Both resorts are oriented primarily toward dedicated spa treatment rather than mass tourism. In both towns, the dominant format is specialised resort hotels with treatment programmes — the real choice is between sanatoriums and their specific methodologies, not hotel categories the way it works in Karlovy Vary.
Mariánské Lázně, due to its larger size, offers a broader selection of sanatoriums and medical centres — dozens of facilities with modern equipment operate here, including a dedicated dialysis centre. Františkovy Lázně is more compact, with a more modest selection, but its programmes are more narrowly tailored to the gynaecological profile.

If, alongside kidney, metabolic, or gynaecological concerns, you’re also interested in treatment for digestive issues, liver conditions, or diabetes, Karlovy Vary — the region’s largest resort, with its own rich cultural programme including the Karlovy Vary International Film Festival — is worth considering.

Choosing between resort specialisations doesn’t have to be a guess. Sanatoriums in both towns admit patients after a consultation with a resort physician, who builds a specific treatment programme based on medical history. Reaching out to a sanatorium for a pre-trip consultation is standard practice, not an extra step.
Mariánské Lázně and Františkovy Lázně aren’t interchangeable “second tier” alternatives to Karlovy Vary. They’re two resorts with genuinely different medical specialisations: one works with kidneys, metabolism, and respiratory health, surrounded by magnificent parks; the other works with gynaecology and skin, in a maximally quiet and compact setting.
The right choice starts with “what do I need treated,” not “which resort is prettier.” Given how close the two towns sit to each other, with enough time you don’t even need to choose — both fit comfortably into a single trip.
