Bad Aachen
mineral-thermal water

Moments of complete well-being, let the natural power of the mineral thermal water of the Aachen springs take effect and let your mind flow to draw new strength in a unique bathing world. Let yourself be pampered and experience the regenerating power of our thermal worlds in many pools at different temperatures.

An inspiring relaxation room with brine graduation system and the soothing “Strokkur” brine steam bath round off the experience to completely switch off for once and gather new energy.

Please note that our outdoor lounging areas are only available seasonally and weather-dependent. However, all attractions, pools, steam baths, and saunas are open all year round.
