The Iconic Vřídlo Geyser Experience

The Hot Spring Colonnade Vřídlo geyser is the main highlight. It is a natural phenomenon that shoots water 12 meters high. The water comes from a depth of 2,500 meters. It is the hottest spring in the city. You can stand in the main hall and feel the warmth. The steam fills the air with a unique mineral scent.

The current building was designed in the 1970s. It uses glass and concrete to create a bright space. You can view the geyser from several angles inside. Large windows allow you to see the spray against the sky. It is a great spot for photography. The power of the water is truly impressive to witness.

• Geyser Hall: Watch the main jet of water erupting constantly.
• Glass Walls: Observe the contrast between the hot steam and the city outside.
• Temperature Displays: Check the digital monitors showing current heat levels.

What to See at the Hot Spring Colonnade Fountains

Beyond the geyser, there are five smaller fountains for tasting. Each fountain offers the same water but at different temperatures. You should learn how hot is the Vřídlo geyser water before you take a sip. The temperatures range from 30°C to 72°C. Drinking this water is a long-standing tradition for health.

You will notice many visitors carrying special porcelain cups. These cups have a long spout for sipping. This design protects your teeth from the high mineral content. You can buy these cups at stalls inside the colonnade. They come in many colors and traditional designs. Savoring the water is a slow, relaxing process.

• Temperature Variations: Taste the water at 30, 50, and 72 degrees Celsius.
• Drinking Fountains: Use the dedicated basins located in the side wings.
• Local Souvenirs: Browse the stalls for unique spa cups and salts.

The Underground Excursion Route

Many people miss the sights hidden beneath the floor. You can book underground tour tickets to see the foundations. This tour takes you into the basement of the colonnade. You will see how the mineral water is distributed. It is a fascinating look at the engineering behind the spa.

The underground also features unique "petrified" items. Local craftsmen place roses and vases in the thermal water. Over time, minerals coat these objects in stone. This process takes several weeks to complete. You can see these items in various stages of petrification. It is one of the most unique things to see in Karlovy Vary.

• Thermal Roses: See how mineral deposits turn paper flowers into stone.
• Historical Pipes: View the old wooden and modern metal distribution systems.
• Rare Minerals: Observe the colorful sinter deposits on the walls.

Common Mistakes and Packing Tips

Many tourists make simple errors when visiting the springs. One major mistake is drinking too much water too quickly. The minerals are very strong and can affect your stomach. It is best to consult a doctor for a proper drinking cure. For a casual visit, just small sips are recommended. Always use a porcelain or glass cup instead of plastic.

Common mistakes to avoid:

• Drinking without a cup: Using plastic bottles can change the water's taste.
• Skipping the underground: Many people only see the geyser hall and leave.
• Ignoring the heat: Touching the hot metal pipes can cause burns.
• Rushing the experience: Give yourself at least an hour to explore fully.
• Arriving late: The fountains often shut off shortly before the building closes.
• Forgetting cash: Some small souvenir stalls do not accept credit cards.

Don't pack these items:

• Heavy backpacks: The underground tunnels are narrow and cramped.
• Fancy high heels: The floors can be wet and slippery near the geyser.
• Large tripods: These can block the path for other visitors in the hall.
• Strong perfumes: The mineral air is part of the therapeutic experience.
