The Vřídlo spring produces approximately 2,000 liters of mineral water per minute.
The water contains high concentrations of dissolved minerals, which create the characteristic 'sinter' crust on surrounding surfaces.
The current building was designed by architect Jaroslav Otruba to replace a 19th-century cast-iron colonnade that was demolished due to corrosion.
Thermal water from the spring is used in the production of the famous Karlovy Vary porcelain and local herbal liqueurs.
The spring is the primary source of heat and mineral water for the city's numerous spa facilities.
The Hot Spring Colonnade in Karlovy Vary houses the Vřídlo, the town's most powerful thermal spring, which erupts up to 12 meters high. The current functionalist-style pavilion, built in 1975, encloses the geyser in a glass and concrete hall. Five distinct thermal mineral water outlets are available for tasting within the colonnade, each varying in temperature. The spring water emerges from the earth at approximately 72 degrees Celsius. Below the colonnade, a complex network of underground corridors allows for specialized guided tours of the sinter crust formations. The site represents the historic heart of the spa town's therapeutic drinking tradition. The structure serves as the primary hub for visitors seeking the curative mineral waters.

Bring a traditional ceramic 'spa cup' or purchase one locally to sip the mineral water directly from the spouts.
Visit the underground tour entrance located within the colonnade to see the technical side of the spring maintenance.
Exercise caution when drinking directly from the spouts, as the water can be extremely hot.
Drinking too much of the thermal water in one sitting, as it has strong laxative effects for those unaccustomed to it.
