Experience the natural power of the Bad Aachener mineral-thermal water

Sanus per Aquam" – healthy through water. Already the old Greeks and Romans knew about the healing power and positive effect of water on body, mind and soul and built magnificent, artfully decorated bath houses, which served cleaning, relaxation and regeneration.

The Carolus Thermen has continued this tradition in the best sense and offers a bathing world without compare in a beautifully designed thermal area. Let the natural power of the healing thermal water fill your senses and experience moments of complete wellbeing.

Eight indoor and outdoor pools of various temperatures with many different attractions, the unique brine steam bath “Strokkur”, a beautiful sun terrace and our wonderful Carolus Beach create the perfect ambience to switch off completely and gather new strength.

Water is the basis of all things,
because water is everything,
and everything returns to water.
(Thales Von Milet)

Indoor Area

An atmospheric setting: the large bathing hall– supported by 18 imposing columns – is the heart of the thermal world.

Our greatest experiences
are not the loudest,
but the most silent hours. (Jean Paul)

Outdoor Area

Pure relaxation - at any time of the year!

Allow yourself a moment of peace
and you will understand
how crazily you were rushing around. (Chinese wisdom)

Bathing Tradition

The more than 30 sulphurous Aachen and Burtscheid mineral thermal springs with a yield of daily 3.5 million litres belong to the richest mineral thermal springs in Germany. With their high share of mineral and trace elements and temperatures of up to 75°C they are moreover among the most popular and hottest thermal springs in Central Europe.

One of these springs is the Aachen “Rosenquelle”. Via a pipeline the Carolus Thermen is continuously supplied with fresh mineral thermal water of best quality. The spring– covered by buildings and well protected – is located in the city centre of Aachen in the Komphausbadstraße. Directly at the source the water temperature is on average 47°C.

In all bathing pools in the indoor and outdoor area, with the exception of the pool in the Oriental Bathing World, you can enjoy the Bad Aachen mineral-thermal water – depending on your preference cold, warm, hot, calm & relaxing or bubbling & wild. The Bad Aachen mineral thermal water has a healing effect at the following complaints:

  • rheumatic disease
  • degenerative illnesses
  • inflammatory and degenerative diseases of the musculoskeletal system
  • rehabilitation after accidents and operations
  • articular gout and osteoporosis
  • dermatoses

our four exceptional
worlds of relaxation.
