Understanding the Hot Spring Underground Tour

The Vridlo Colonnade is the heart of the city's thermal activity. It houses the most powerful hot spring in the region. Karlovy Vary is recognized as a UNESCO World Heritage site for its spa culture. The underground tour reveals the complex system of pipes and mineral deposits.

You will walk through historic tunnels that date back many years. These tunnels protect the springs and allow workers to maintain the colonnade. You can see how the thermal water creates unique stone formations over time. It is a fascinating look at the natural forces beneath the streets.

Tours are led by guides who explain the history and geology. Most tours last about 45 to 60 minutes. Because space is limited in the narrow tunnels, group sizes are kept small. This makes it essential to understand how to buy tickets for Karlovy Vary underground tour before you arrive.
