The healing properties of the mud are believed to be due to the unique combination of sea, soil, and climate of Klimno Bay. The mud is naturally heated by the sun and mixed with sea salt, which enhances its therapeutic effects. Furthermore, this region is rich in minerals and organic substances known to treat a variety of conditions, including skin diseases, rheumatic diseases, and other inflammations. All of this has made Klimno Bay a significant destination for health tourism, contributing to the local economy and preserving this historical tradition.
