The Vřídlo Hot Spring Geyser Experience

The Vřídlo geyser is a natural wonder in the heart of the city. It shoots up to 12 meters into the air. This spring provides water for many local spa hotels. You can see it inside a modern glass building. The air inside the colonnade is warm and smells slightly of minerals.

Is it safe to drink Vřídlo thermal water for everyone? Generally, a small taste is perfectly fine for healthy adults. The water contains high levels of salt and minerals. It has been used for healing since the 14th century. You can learn more about the city’s history at the official Karlovy Vary tourism site.

Most people find the taste quite strong and salty. It is often described as having a metallic or "eggy" flavor. This comes from the natural sulfur and iron. Do not be surprised by the heat. The water is cooled to different temperatures at various drinking fountains.

Is it Safe to Drink Vřídlo Thermal Water Every Day?

While it is safe to taste the water, drinking it as a treatment is different. Local doctors prescribe specific amounts for various health issues. You should not drink large amounts without medical advice. The minerals can affect your digestion or blood pressure. For a single visit, a few sips are perfectly safe.

Always use a porcelain or glass cup. Plastic bottles are not recommended for hot thermal water. The heat can cause chemicals from plastic to leach into the water. Plus, the spout on a traditional spa cup helps cool the water. It also protects your tooth enamel from the minerals.

Remember to drink the water while walking slowly. This is the traditional way to absorb the minerals. Most people visit the colonnades in the morning or late afternoon. Enjoy the atmosphere and take your time. This ritual is a key part of the Karlovy Vary experience.
