The 5 Mineral Springs of the Mill Colonnade

When asking how many springs are in the Mill Colonnade, the answer is five unique sources. These springs are numbered to help visitors navigate the drinking cure. Each spring has a different temperature and mineral balance. The Mill Colonnade was designed by architect Josef Zítek in the late 19th century. It features 124 Corinthian columns and beautiful stone reliefs. Walking through this hall feels like stepping back in time. You will see locals and tourists alike carrying traditional porcelain cups.

The springs located here include the Mill Spring, Rusalka, Prince Wenceslas, Libuše, and Rock Spring. While there are five sources, Prince Wenceslas has two separate outlets. This can sometimes confuse visitors about the total count. Always check the temperature displays before sipping. Some waters are quite hot and can be surprising. Most are rich in bicarbonate, sulphate, and chloride. These minerals are believed to aid digestion and metabolic health.

Planning Your Visit to the Mill Colonnade

Visiting the springs is easy as they are open 24/7. However, the best time to go is early morning. You can avoid the large tour groups that arrive midday. Most visitors spend about an hour exploring the colonnade's length. Remember that the water is for sipping, not for filling large bottles. Respect the local tradition by using a proper porcelain cup. These are sold at almost every corner in the spa zone.

Karlovy Vary is a very walkable city for most people. If you arrive by train, the Karlovy Vary railway station is a short bus ride away. The town is also well-connected by the local public transport authority. Wear comfortable shoes as the promenade is long and paved with stone. Many visitors choose to stay for a few days to fully experience the spa treatments. This allows you to try all five springs at a relaxed pace.
