Underground of the Thermal Spring

Ticket price

The tour in the historical part of the Vridlo hot spring underground shows visitors the production of traditional Karlovy Vary souvenirs, the so-called "stone roses". You can see a collection of calc-sinters and accreted aragonite, clogged-up pipes from the early 20th century, or rare bacteria and algae that thrive on surfaces which are washed by hot spring water. The visitors can also learn some points of interest about the Vridlo colonnade, its history, its unique subsoil, and of course about Karlovy Vary’s best known hot spring, the Vridlo.
