Karlovy Vary Springs: What Is the Difference Between Them and How to Choose the Right One
Introduction
Karlovy Vary is famous for its mineral springs, yet many visitors are surprised by one fact:
all springs have a similar composition, but are used differently in treatment. Why?

The answer lies in subtle differences:
- temperature
- CO₂ content
- flow dynamics
- mineral concentration
These factors allow doctors to tailor treatments individually for each patient.
How Many Springs Are There in Karlovy Vary
There are more than 15 thermal springs available for drinking therapy.
The most famous include:
- Vřídlo
- Mill Colonnade springs
- Libuše spring
- Rusalka spring
- Charles IV spring
- Castle spring
👉 All originate from the same underground source but differ at the surface.

Do All Springs Have the Same Composition
Partially — yes.
All belong to:
bicarbonate–sulfate–sodium mineral waters
However, they differ in:
- temperature (approx. 30°C to 73°C)
- mineral concentration
- CO₂ saturation
- flow characteristics
💡 Even small differences create different physiological effects.
Temperature as the Key Difference
Hot springs (60–73°C)
Example: Vřídlo
Effects:
- muscle relaxation
- reduced stomach acidity
- gentle impact on digestion
Recommended for:
- high acidity gastritis
- spasms
Medium-temperature springs (45–60°C)
Examples: Mill, Libuše
Effects:
- liver stimulation
- improved digestion
Recommended for:
- liver conditions
- bile-related issues
Cooler springs (30–45°C)
Examples: Rusalka, Charles IV
Effects:
- stimulation of gastric secretion
- activation of digestion
Recommended for:
- low stomach acidity
- slow metabolism
The Role of CO₂
CO₂ affects:
- taste
- absorption rate
- vascular response
More carbonated water:
- stimulates digestion more actively
Less carbonated:
- acts more gently
Mineral Concentration
Although similar in composition, slight variations in concentration affect:
- intensity of the effect
- load on the body
👉 Higher concentrations require careful use.
Flow Dynamics and Pressure
Another important factor:
- Vřídlo is a powerful geyser
- others have gentle flow
This influences:
- temperature
- gas content
- structure of the water
How Doctors Choose the Right Spring
Treatment in Karlovy Vary is always individualized.
Doctors consider:
- diagnosis
- stomach acidity
- liver function
- metabolism
👉 Based on this, they select:
- the appropriate spring
- temperature
- drinking schedule
Example 1: High Acidity
- hot springs
- drinking before meals
Example 2: Liver Conditions
- medium temperature
- structured intake
Example 3: Slow Digestion
- cooler springs
- drinking closer to meals
Can You Choose a Spring Yourself
Technically yes, but not recommended.
Reasons:
- risk of incorrect selection
- reduced effectiveness
- possible discomfort
👉 A medical consultation is the best approach.

Conclusion
Karlovy Vary springs differ not so much in composition, but in:
- temperature
- mineral concentration
- CO₂ content
- flow dynamics
👉 These factors make personalized treatment possible.
