Safety & Etiquette

Aquae Calidae Aqua Centre Safety Tips

Aquae Calidae Aqua Centre provides specific safety guidance for mineral water bathing. Before entering the warm hall, gradually acclimatise in the lobby and shower areas. The body must be clean before entering any pool; remove cosmetic and medical products by washing thoroughly before entry. The maximum stay in the aqua centre is 2 hours per visit. The maximum stay in the mineral water pools is 20 minutes per session; the body should be at rest throughout, with no swimming or intense movement. Rest between pool sessions and rehydrate with the mineral drinking water available at the complex.

The sauna operates at 90 degrees Celsius; the maximum recommended stay is 15 minutes. High temperature dilates blood vessels and stimulates circulation; cool down fully at the cold pool after sauna use before re-entering any warm area. People with cardiovascular conditions, rhythm disorders, thyrotoxicosis, epilepsy, infectious diseases, or active-stage medical conditions should not use the facility; these are formal contraindications listed by the centre's official guidance. Pregnant women and people with oncological conditions should also avoid balneotherapy.

Children must be supervised at all times at the children's pool; jumping and games in the mineral pools are not permitted. The complex is closed on Mondays; confirm current opening times at aquae-calidae.com before visiting. The 3D cinema and archaeological museum areas are separate from the aqua centre and can be visited before or after the spa session; the combined ticket is recommended for a full visit. Towels and flip-flops are recommended; bringing your own saves rental cost.

What is the history of Aquae Calidae?

Aquae Calidae, Latin for warm waters, is one of the oldest continuously used thermal bathing sites in Europe. The hot springs at the Vetren site near Burgas were first used in the Neolithic period, between the 6th and 5th millennium BC. The Thracians built a sanctuary to the Three Healer Nymphs at the springs; the Romans expanded this into major public baths from around 72 BC onward. Significant visitors included Philip II of Macedon, Roman emperors Justinian I and Constantine IV, Bulgarian ruler Tervel, and Ottoman sultan Suleiman the Magnificent, whose bath has been fully restored and is now part of the museum complex. The site operated as thermal baths continuously for over 1,700 years.
