What do I need to bring for a smooth stay?


If you would like to bathe in our thermal world, you will need suitable swimwear, shower gel, at least one towel and bathing slippers are also recommended.


Should you visit our sauna area, then we recommend two towels as large as possible – one to lay underneath during the sauna sessions, one to dry off after the shower. In addition, a cosy bathrobe, in which you can snuggle up while having a rest.


You are perfectly dressed for your spa visit with a large towel or bathrobe.


If you do not bring large towels or a bathrobe, you can borrow these items from our Carolus Shop daily between 9:30 a.m. and 8:30 p.m. for a fee.

Can I bring infants and toddlers?


As our pools are filled with very mineral-rich thermal water, the minerals would penetrate the body of small children through their thin skin much faster and more intensively than in the case of adults. Doctors therefore advise not to let small children bathe in such mineral-rich thermal water.


Therefore, for the protection of children, we only allow them to be guests of Carolus Thermen from the age of six.


(We reserve the right to insist on confirmation of age details by official photo IDs or similar).

Are there any other age restrictions?


Children/youngsters from the ages of 6 to 15 must be accompanied by an adult.


(We reserve the right to insist on confirmation of age details by official photo IDs or similar).

Is the entrance also possible for a pregnant person?


Pregnant women are very welcome at the Carolus Thermen. However, please note that every pregnant woman can react differently to a visit of the thermal baths (thermal bath, sauna world & Carolus Spa). Therefore we recommend a short consultation with your doctor.

Is the access to the Carolus Thermen barrier-free?


Of course, almost all areas of the Carolus Thermen are also accessible to people with walking disabilities. Elevators guarantee accessibility to the various levels, two handicapped accessible dressing rooms allow safe and comfortable changing and a lift in the bathing hall allows easy access to the large thermal water pool.
