About Interhotel Sandanski Thermal Pools
Interhotel Sandanski Thermal Pools, Bulgaria is a four-star hotel and balneotherapy complex at Ul. Okolovrastno Shose in Sandanski, Blagoevgrad Province, southwestern Bulgaria. The hotel is in the centre of Sandanski, adjacent to the large city park, 160 kilometres south of Sofia and 20 kilometres from the Greek border. Sandanski is considered the warmest town in Bulgaria due to its sheltered position at the foot of the Pirin Mountains and its mild year-round climate, which is particularly recommended for people with asthma and respiratory conditions.
The mineral water complex includes three pools all filled with natural mineral water: an outdoor pool (12.5m by 6.5m, 30 to 32 degrees Celsius), a large indoor pool (25m by 12.5m, 30 to 32 degrees Celsius), and an outdoor thermal pool at 36 to 38 degrees Celsius with lifeguards on duty. The three-level spa is one of the largest balneotherapy centres in Bulgaria, offering aroma and mineral salt baths, sauna, steam bath, hydrotherapy treatments, remineralising algae baths, and a wide range of massages. Medical treatments cover metabolic disorders, asthma, locomotory system conditions, and neurological problems. The hotel has 285 rooms, three restaurants, and five tennis courts.

Safety & Etiquette
Interhotel Sandanski Thermal Pools Safety Tips
Interhotel Sandanski Thermal Pools is generally safe as a fully staffed four-star hotel with lifeguards on duty at the outdoor thermal pool and trained staff throughout the spa centre. The main considerations relate to the mineral water temperatures and the balneotherapy centre protocols.
The outdoor thermal pool operates at 36 to 38 degrees Celsius, which is warm enough to cause heat build-up in extended soaking sessions. Limit continuous soaking to 15 to 20 minutes, exit to rest in the shade between sessions, and drink water regularly. The indoor and outdoor main pools at 30 to 32 degrees Celsius are more moderate and suitable for longer periods. People with heart conditions, hypertension, asthma, or open wounds should consult a doctor before using the thermal pool; the on-site medical balneotherapy centre can provide guidance on suitability. Pregnant visitors should seek medical advice before using the thermal pool or any spa treatments.
Wet pool surfaces and movement between pool areas present a slip risk; wear pool sandals throughout. Sunbeds around the outdoor pools can be in high demand on summer weekends and holidays; arrival early in the morning improves access. The outdoor pools may occasionally be closed for maintenance; the thermal pool typically remains available. Valuables should be left in the room safe or locker before accessing pool areas. Pets are not permitted. Children under 12 must be accompanied and supervised by adults at all times near pool areas.
