Understanding the Vřídlo Geyser Temperature

The Vřídlo geyser is a marvel of nature. The water temperature is a constant 72°C (162°F). This makes it the hottest thermal spring in the country. The water comes from a depth of about 2,500 meters. It carries rich minerals that people have used for healing for centuries. You can see this steam rising from the Hot Spring Colonnade Vřídlo geyser every day.

Because the water is so hot, you cannot drink it directly from the main fountain. The Colonnade features several smaller drinking basins. These basins cool the water to different temperatures. Some are 50°C, while others are closer to 30°C. This allows visitors to sip the mineral-rich water comfortably. Always use a traditional porcelain spa cup for the best experience.

The heat of the water also powers the local spa industry. Many hotels use this thermal water for baths and treatments. It is important to follow medical advice if you plan to drink large amounts. The high mineral content can affect your digestion. Most people enjoy a small glass while walking through the beautiful city center.

Practical Tips for Visiting Karlovy Vary

When visiting the UNESCO World Heritage site of Karlovy Vary, timing is everything. The town gets very busy during the International Film Festival in July. For a quieter experience, visit in late spring or early autumn. Most springs are accessible 24/7, but the Vřídlo hall has specific opening hours. Check the Karlovy Vary Official Tourism site for current schedules.

Public transport is very efficient in the city. You can use local buses to reach the outer districts or the station. Information on tickets is available via Dopravní podnik Karlovy Vary. Most of the spa zone is pedestrian-only, so prepare for plenty of walking. Wear comfortable shoes to handle the cobblestone streets.

Finally, remember to respect the local spa etiquette. The colonnades are places of healing and relaxation. Keep noise levels down while people are drinking from the springs. Do not use soap or touch the water inside the drinking basins. This keeps the mineral water clean for everyone to enjoy.
