The Mineral Springs of Luhačovice and Their Counterparts Around the World

What Makes the Luhačovice Springs Unique

Luhačovice is the fourth-largest spa town in the Czech Republic and the most visited spa town in Moravia. Its more than 350-year-old spa tradition is based on a unique natural phenomenon: the Luhačovice mineral springs are remnants of a Tertiary sea that stretched across what is now the White Carpathians millions of years ago. This fossil seawater remained trapped between layers of flysch rock and has since been enriched with deep carbon dioxide, which rises along tectonic faults from the depths of the Earth’s crust.

A total of 15 natural healing springs emerge in the Luhačovice area, 13 of which are actively utilized. All belong to the category of cold hydrogen carbonate-chloride-sodium acidulous waters (HCO₃-Cl-Na) with a high carbon dioxide content. It is precisely this combination of properties that is exceptionally rare in a global context:

• Fossil marine origin — these are not rainwaters enriched by passing through rocks, as is the case with most mineral waters in the world, but rather metamorphosed remnants of a Tertiary sea
• High mineralization — 9,000 to 16,456 mg/l, which is many times higher than that of ordinary mineral waters
• Low temperature — 10–14 °C, which is unusual for waters with this level of mineralization (most highly mineralized waters in the world are thermal waters)
• Natural CO₂ saturation — 2,000 to 3,100 mg/l, significantly higher than in most European mineral waters
• Iodine — in concentrations exceptional for non-petroleum seawater (Vincentka contains 5.2 mg/l of iodine, or 348% of the reference daily value)
• Rare trace elements — lithium, barium, boron, fluorine, and dozens of others

The Luhačovice area is situated on a prominent anticlinal fold disrupted by a fault system. The most significant is the Nezdenice Fault, the main pathway for the release of deep CO₂, which drives the entire hydrological system. The presence of iodine is a key indicator of the water’s origin: iodine occurs in such concentrations almost exclusively in waters associated with oil deposits. The waters of Luhačovice are metamorphosed waters of oil domes—a theory confirmed by Associate Professor Václav Zýka in 1957.

Vincentka — Luhačovice’s flagship

Vincentka is the reference spring and the most famous healing water of Luhačovice. It is bottled and distributed throughout the Czech Republic and Slovakia. Its chemical profile shows why the Luhačovice springs are so exceptional:

Among the trace elements in Vincentka are boron, beryllium, silver, nickel, tin, titanium, zinc, manganese, copper, strontium, and aluminum. With a total mineralization of 9,060 mg/l, it ranks among the most mineral-rich waters—Elektra, with 16,456 mg/l, is the most mineral-rich spring in Luhačovice and one of the most concentrated sources in all of Central Europe.

The question we ask ourselves is: are there springs anywhere in the world with a similar chemical profile? The answer is yes—but only a handful of places on Earth truly come close to Luhačovice.

The world’s most similar springs

Based on six key criteria—hydrochemical type (HCO₃-Cl-Na), iodine content, natural CO₂ saturation, fossil marine origin, total mineralization, and the presence of rare trace elements—we have identified six locations that most closely resemble the Luhačovice springs. You can find all of them on our interactive map of global analogues.

Essentuki, Caucasus, Russia — the closest analog in the world ⭐⭐⭐⭐⭐

Distance from Luhačovice: approximately 2,500 km as the crow flies

Essentuki is located in the Stavropol Krai at the northern foothills of the Caucasus and is part of the famous Caucasian Mineral Waters region, which also includes Kislovodsk and Pyatigorsk. The city is famous for Springs No. 4 and No. 17—sodium-chloride alkaline waters with a mineralization of around 13,000 mg/l, natural CO_2, and iodine content. The Essentuki-17 spring, with approximately 5,500 mg/l of bicarbonates, 2,400 mg/l of chlorides, and 2,000 mg/l _of CO_2, exhibits the chemical profile most similar to Vincentka among all the world’s springs. The geological principle is identical: metamorphosed fossil seawater in the sedimentary rocks of the Alpine-Caucasian flysch belt, enriched with deep CO₂ along tectonic faults. At the Essentuki spa, diseases of the digestive system, respiratory tract, and metabolism are treated—through drinking cures, inhalations, and baths, i.e., the same methods as in Luhačovice. The city offers dozens of sanatoriums, and Essentuki No. 17 water, as a bottled mineral water, is one of the best-selling in all of Russia and the post-Soviet space.

Krynica-Zdrój and Muszyna, Poland — geological siblings ⭐⭐⭐⭐⭐

Distance from Luhačovice: approximately 200 km as the crow flies

Krynica-Zdrój and neighboring Muszyna in the Polish Beskids are, of all the world’s locations, geologically the closest relatives to Luhačovice. They lie within the same Magura flysch zone—they are literally geological siblings with the same type of rock, the same mechanism of water formation, and the same fossil marine origin. Krynica has 23 mineral springs, the most famous of which is Zuber, with a mineralization of around 22,000 mg/l—even stronger than Luhačovice’s most concentrated spring, Elektra. Other springs, Jan (~14,000 mg/l) and Słotwinka (~8,000 mg/l), are similar in composition to Vincentka. Krynica is one of the largest health resorts in Poland, treating diseases of the digestive system, liver, gallbladder, diabetes, and metabolic disorders. At the turn of the 19th and 20th centuries, both spas—Krynica and Luhačovice—were part of the same Austro-Hungarian imperial spa circuit and were popular destinations for the Czech and Polish intelligentsia.

Saratoga Springs, New York, USA — American counterpart ⭐⭐⭐⭐⭐

Distance from Luhačovice: approximately 8,000 km as the crow flies

Saratoga Springs, New York, is an American spa town with over 200 years of history. The Mohawks have used the local springs since ancient times and believed that the water bubbling from the ground was a gift from the god Manitou. The famous Congress Spring, discovered in 1792 and scientifically analyzed in 1842, exhibits a mineralization of 8,000 to 15,000 mg/l, of the HCO₃-Cl-Na type with iodine, bromine, and natural CO₂ at a cold temperature of 10–12 °C—remarkably close to the Luhačovice profile. The water also has a fossil marine origin from the Appalachian Sedimentary Basin. In the 19th century, Saratoga Springs was a destination for the wealthy New York and Boston elite, who came here for spa treatments. In the early 20th century, the state of New York took action against the industrial extraction of CO₂ gas, which threatened the springs, and established the protected Saratoga Spa State Park. Compared to Luhačovice, the Saratoga springs have a higher calcium and magnesium content (harder water), less lithium and barium, and are not used for inhalations—the American spa model is traditionally more focused on relaxation.

Borjomi, Georgia — the best-known commercial equivalent ⭐⭐⭐⭐

Distance from Luhačovice: approximately 2,800 km as the crow flies

Borjomi is arguably the most famous mineral water in the entire post-Soviet region. Historically referred to as the “Caucasian Vichy,” this naturally carbonated water is exported to more than 40 countries worldwide and constitutes a significant portion of Georgia’s exports. In the 1980s, annual production reached 400 million bottles. The town of Borjomi, with a population of 15,000, attracts thousands of tourists who come to the local spa resorts—a tradition dating back to the 1820s, when Russian soldiers began using the local baths. Famous guests included Anton Chekhov, Pyotr Tchaikovsky, and the imperial family. Chemically, Borjomi is a purer HCO₃-Na type with a mineralization of 3,500 to 5,900 mg/l—roughly half that of Vincentka. It shares the boron component and natural CO₂, but lacks the significant iodine and chloride content characteristic of Luhačovice waters.

Bad Nauheim, Germany — the spa town where Elvis stayed ⭐⭐⭐⭐

Distance from Luhačovice: approximately 750 km as the crow flies

Bad Nauheim, located in the Hessian region of Germany, belongs—along with Bad Kissingen and Bad Ems—to a group of German mineral spas featuring HCO₃-Cl-Na springs with a mineralization of 7,000 to 15,000 mg/l, containing iodine, bromine, and natural CO₂. Bad Nauheim is also well-known outside the spa world: Elvis Presley lived here during his military service from 1958 to 1960, and the town still hosts the annual European Elvis Festival. From a balneological perspective, the local Art Nouveau Sprudelhof and healing springs are used primarily to treat heart disease and back pain. Bad Kissingen, a favorite destination of Bismarck and the Russian tsars, has springs directly comparable to those in Luhačovice, including their iodine and bromine content. Bad Ems became famous as one of the most exclusive European spa towns of the 19th century—Napoleon III and Prussian King William I caused a diplomatic incident here in 1870 known as the Ems Dispatch.

Skhidnytsia and Truskavets, Ukraine — Carpathian siblings ⭐⭐⭐⭐

Distance from Luhačovice: approximately 500 km as the crow flies

Truskavets and neighboring Skhidnytsia in the Lviv region lie in the outer flysch zone of the Carpathians, that is, in the direct geological continuation of the Luhačovice spring structure toward the east. Truskavets, one of the largest and oldest balneological spa towns in Europe, boasts 14 healing mineral springs and welcomes around 200,000 visitors annually. The most famous is Naftusia water—a low-mineralized water containing organic components of petroleum origin, used to treat the kidneys and urinary tract, which is unparalleled anywhere in the world. In addition to Naftusia, however, the area also offers stronger carbonate-bicarbonate-sodium waters with a mineralization of 8,000 to 11,000 mg/l and a fluoride content similar to that of Luhačovice. Some of the springs contain iodine and bromine from a paleomarine environment. The area is also a globally unique deposit of ozokerite (mountain wax), from which the therapeutic salt Barabara is extracted.

Why It Is Difficult to Find a Copy of Luhačovice

A comparison of the six most similar locations in the world leads to a clear conclusion: no place on Earth offers an exact replica of the Luhačovice mineral profile. Each of the analogues shares some characteristics with Luhačovice, but none replicates the entire combination:

• Essentuki are chemically the most similar, but have slightly lower levels of barium and metaboric acid
• Krynica is geologically the closest (same flysch belt); some springs are even stronger
• Saratoga Springs shares a fossil origin, cold temperatures, and iodine, but has harder water and less lithium
• Borjomi is the world’s most famous, but its mineralization is only half as high and it lacks iodine
• Bad Nauheim and its surrounding spas have a similar chemical profile, but the springs are slightly warmer
• Truskavets offers geologically related waters, yet its most famous spring, Naftusia, is of a completely different type

The reason is simple: the Luhačovice springs were formed by a unique combination of geological conditions—fossil seawater trapped in the flysch rocks of the White Carpathians, enriched by deep juvenile CO₂ along the Nezdenice Fault, with iodine from oil domes and rare trace elements from contact with Paleogene sandstones. This specific geological history is repeated on Earth only in fragments and never in its entirety.

No springs with a complete match have been identified on the continents of South America, Africa, and Oceania—thermal systems there are usually of volcanic origin and have a different chemical profile. Luhačovice thus remains a true rarity in global balneology.
