This specialist postgraduate thesis aims to investigate the concept of sustainable cruising tourism. This particular form of tourism seeks to promote the development of the community economy, provide an appropriate tourist experience, improve the quality of life of residents and contribute to environmental protection by minimizing environmental adverse effects and by emphasizing the importance of implementing it in today's modern tourism age. The problem of the research of this specialist postgraduate thesis is the fact that there still needs to be more recognition of the importance and role of sustainable development. The main hypothesis of this thesis "Development of sustainable cruising tourism contributes to the development of the local community economy, improvement of social relations and environmental protection " was tested on the example of a selected case study, the city of Dubrovnik. Dubrovnik is an extremely attractive tourist destination facing many challenges (too many simultaneous visitors, traffic jams in the destination, endangering cultural diversity, impact on the tolerance threshold of tourists and the tolerance threshold of locals, impact on the marine environment, etc.). On the example of the port of Dubrovnik, it is investigated whether there is a possibility of sustainable development of cruising tourism. The potential in many destinations today is not used due to inadequate management. In addition to the numerous positive effects of cruising tourism development (contribution to economic development, employment of the population, reduced number of tables and chairs in the historic centre to increase the public space available to all visitors, reduction of the number of souvenir shops located in public spaces etc.), is often accompanied by numerous negative effects: pollution of the sea and air, exceeding the capacity of the reception, degradation of space, etc. Sustainable development and its implementation into cruise tourism are to become imperative today.
