The main topic of this final project is the development of health tourism. It is primarily based on health tourism in the Republic of Croatia. In this project can be gleaned the introductory-theoretical part, which at the very beginning summarizes all previous experiences and information on the basis of which individual conclusions were made. At the very beginning, the definition of tourism is explained in more detail, as well as the definition of health tourism. Nature has given us healing springs on the basis of which health tourism has been created in many European countries, as well as in the Republic of Croatia. The health resorts and the appropriate climatic conditions have in a perfect way encouraged and exerted a strong influence on the general development of tourism. The main problem in the development of health tourism in Croatia and the subject of research is the renovation and reconstruction of spas, spas and specialized hospitals. Due to the proximity of countries that abound in large markets, are rich in natural beauty and favorable climatic conditions, are safe countries with competitive prices and a long tradition, Croatia has comparative advantages for the development of health tourism. Health tourism products include: wellness tourism, spa tourism and medical tourism. Health tourism is a complex tourism product that annually records a growth of 15-20% worldwide. By investing in health tourism, the entire tourist offer is raised, which is especially important, as well as the awareness of a healthy lifestyle and taking care of one's own health. I believe that additional investment in the renovation and reconstruction of Croatian health resorts would further increase the number of users of services in health tourism, and thus tourism in general in the Republic of Croatia.
