Understanding the Heat of the Vridlo Geyser

The Vridlo Hot Spring is the hottest source in the region. Many visitors ask, how hot is the Vridlo geyser water exactly? The water reaches a temperature of approximately 72 degrees Celsius (162 degrees Fahrenheit). This heat comes from deep underground sources. The water contains high levels of minerals like lithium and sulfur.

The geyser is incredibly powerful. It yields about 2,000 liters of mineral water every minute. The pressure forces the water to spout up to 12 meters high. You can see this display inside the modern Hot Spring Colonnade. It is a striking sight that symbolizes the town's spa tradition. Learning about the Vridlo Hot Spring Geyser is essential for any traveler.

Because the water is so hot, you must be careful. You should only drink it from the designated smaller fountains. These fountains cool the water to various temperatures for drinking. Local doctors often prescribe specific springs for health treatments. Always use a traditional porcelain spa cup to sip the water slowly.
