In the Caracalla Spa, with over 4000m² of space, you will find a wonderful atmosphere and plenty of room to relax and unwind. An all-round sense of wellbeing exudes from the bathing area with its ancient temple feel, the sauna complex and the stylish WellnessLounge. And coming across thermal water that is as rich in minerals as Baden-Baden's is hard to find. For more than two millennia, it has been bubbling to the surface here, from a depth of 2000 metres and with temperatures of up to 68°C, where it has been able to unleash its renowned, beneficial effects on body and soul.
Origins of the thermal water
At the foot of the Florentinerberg hill in Baden-Baden there are twelve separate, sodium chloride-bearing artesian springs. Rising from depths of between 1200 and 1800 metres, the waters reach the surface at temperatures ranging between 56°C and 68.8°C.
The names of the 12 springs are as follows: Kühler Brunnen, Lauer Brunnen, Brühquelle, Fettquelle, Höllquelle, Murquelle, Florentinerquelle, Klosterquelle, Freibadquelle, Friedrichsquelle, Schwarzwaldquelle and Judenquelle. At the end of the 19th Century three underground catchment tunnels (Friedrichsstollen, Kirchenstollen and Neuer Stollen) were created to consolidate the springs The Friedrichsstollen is the main tunnel delivering around 50% of the total thermal water supply. Today the Caracalla Spa and Friedrichsbad are supplied with a mixture of water from the three tunnels.
The springs are approximately 12,000 - 17,000 years old and discharge around 800,000 litres of thermal water a day (that's 9 litres a second) with a daily mineral content of 2,400 kg. As a result, the concentration of minerals in Baden-Baden's thermal water is one of the highest in the state of Baden-Württemberg.
The Friedrichsstollen is the main tunnel delivering around 50% of the total thermal water supply. The water in the Friedrichsstollen has a number of special features that we have put together in a PDF.

As a result, the concentration of minerals in Baden-Baden's thermal water is one of the highest in the state of Baden-Württemberg. The thermal spring water of Baden-Baden is also referred to as natrium-chloride thermae containing fluoride. The water gets its mild salty taste from these two main elements.
The mineral-rich Baden-Baden thermal water regenerates, stimulates and activates the entire body. It also has a relaxing effect on the muscles and helps to alleviate stress. The thermal water of the Caracalla Spa contains active agents that have a specific impact on your body. In order to achieve the best results, the thermal water should be enjoyed in moderation.
Immerse yourself in Baden-Baden's liquid gold and relish the beneficial effects on mind, body and soul.
On Mondays to Fridays (except public holidays) at 11.30am, visitors to the Caracalla Spa are invited to join a 20-minute water gymnastics course free of charge. Under the guidance of an experienced therapist, exercises are performed to stretch and strengthen muscles in the spa's large indoor pool.
The hot thermal water has a supportive effect and offers resistance. Water is considerably denser than air meaning that more effort is required to move your body in water. But because of the buoyant force, this increase in effort goes largely unnoticed. For instance, when standing chest-high in water, your body feels 20% lighter meaning that exercising in water produces excellent results. In addition to this, the hydrostatic pressure helps to protect your joints, tendons and vertebrae, and the dissolved minerals in the water also boost the immune system.
Unlike many other sporting activities, water gymnastics helps you keep your whole body in shape and not just individual parts.
