Aloiska: the oldest spring with healing properties for digestion

The Aloiska Spring is one of the oldest and most potent mineral springs in Luhačovice. Its rich history, dating back to before 1770, its exceptionally high mineral content, and its traditional focus on treating digestive disorders make it a unique resource that has attracted spa visitors for over two and a half centuries.

One of the oldest springs

There are records of mineral water springing up above today’s Bílá čtvrť dating back to before 1770, which ranks Aloiska among the very oldest documented springs in Luhačovice. Over the centuries, it has been called by various names—Lesní pramen, Pramen v hoře, or Luisin pramen. It has been actively used for spa purposes since the 1820s.

In the 20th century, the flow rate of the original spring began to decline. The old spring was therefore closed and redirected into a 14.4-meter-deep well, where it received its definitive name, Aloiska. The current appearance of the wooden pavilion above the spring dates back to 1963. The pavilion, complete with a service counter, still serves visitors as a pleasant spot for drinking cures amidst the greenery.

Exceptional Mineralization

With a total mineralization of 12,987 mg/l, Aloiska is the second strongest spring in Luhačovice—surpassed only by Elektra, with a value of 16,456 mg/l. For comparison: Vincentka has 9,060 mg/l and Ottovka 9,725 mg/l.

Aloiska is a naturally highly mineralized cold water of the hydrogen carbonate-chloride-sodium type (HCO₃-Cl-Na) with rich natural carbonation. Its key components include:

Iodine (I⁻) — supports thyroid function, boosts immunity
Iron (Fe) — contributes to hemoglobin formation and oxygen transport
Metaboric acid (HBO₂) — anti-inflammatory and antiseptic effects
Bicarbonates (HCO₃⁻) — an alkaline component essential for the digestive system
Trace elements — lithium, barium, fluorine, strontium, and other specific components of Luhačovice waters

The high concentration of minerals is evidence of the water’s long contact with deep layers of flysch rock — Aloiska draws from layers where fossil seawater has been enriched with minerals for tens of thousands of years (source: GeoERA, 2021).

Digestive Specialist

Aloiska is traditionally considered the ideal mineral water for drinking cures for digestive disorders. Its high bicarbonate content effectively neutralizes stomach acid and alleviates:

Chronic inflammation of the stomach (gastritis)
Stomach and duodenal ulcers
Heartburn and gastroesophageal reflux
Functional dyspepsia (discomfort after eating)
Conditions following digestive tract surgery

In addition to drinking cures, Aloiska is also used for inhalations—its iodine and chloride content helps with chronic respiratory diseases. Luhačovice mineral waters are generally beneficial for people with diabetes, circulatory disorders, and during recovery after cancer treatment.

Flow Rate and Accessibility

Aloiska’s flow rate is 3 liters per minute—just like Ottovka, this is a modest output, corresponding to the deep and slow seepage of mineral water through underground layers. For comparison: Nový Jubilejní, the most abundant public spring, delivers 60 liters per minute.

Where to find Aloiska

Aloiska springs up in the park above the Bílá Quarter, at the southwestern foot of Velká Kamenná—approximately 30 meters higher than most other springs. It is precisely this elevated location that contributes to its specific composition. The wooden pavilion with a service counter is nestled among mature greenery and offers a peaceful setting for a drinking cure.

From the spa colonnade, you can reach Aloiska with a pleasant walk uphill—the walk takes about 10 minutes and offers beautiful views of the spa center. The exact location is shown on the interactive map of springs.
