Swimming becomes floating: dive in and let yourself be carried by the 33 °C warm water.

In the SoleRelaxpool, high-quality 6-percent Sülbeck natural brine is used, extracted from a depth of 400 metres at the foot of the Harz Mountains. The valuable minerals in our thermal bath have a positive effect on the body, and the feeling of weightlessness also relaxes the mind.



Every day from 8.00 p.m., guests enjoy the bath in the SoleRelaxpool exclusively textile-free. 


Tariff SoleRelaxpool: per 20 min. € 2.50.
