Health tourism in Ulcinj, due to its extraordinary factors, the clean and clear sea, the curing sandy beaches, the sulfur mineral water, the curing mud, the sea salt, and its stem alkalis, the mild stimulative coastal climate, Ulcinj is a natural spa with perfect qualities, well known all over the world. Prof. Not (Noht), the manager of the Institute for Tropical Diseases in Hamburg, made the following statement as he was staying in Ulcinj in 1925: “I have never seen a place filled up by stars as it is Ulcinj“. The value of this area is great and versatile for the human body, and professor Dr. Lemoh (Lemoch), president of the European League for Rheumatism, while staying in Ulcinj in 1964 said: “In a therapeutic sense Ulcinj has got a great future“. A scientist of a worldwide reputation Mihailo Pupin demanded in June 1919 through his deputy from the Ministry of Internal Affairs of the Kingdom of Montenegro a license for opening a sanatorium for treating certain conditions and diseases. All this contributed to the fact that in 1929 Ulcinj was claimed to be „a spa and climatic resort“ by the decree of the Kingdom of Yugoslavia. The advantages of the Ulcinj climate are most significant for its living conditions, and the sea temperature ensures the possibility of sunbathing for 6 months, from May to October. In summer the sea transparency reaches 38 m and on the open sea in front of Ulcinj, it measured even 56 m which was the highest level in the Adriatic Sea.
