Despite the important role of tourism in the economic growth of the islands, many challenges and issues remain unresolved. These problems include traffic isolation, lack of infrastructure, demographic difficulties, lack of job opportunities, and other factors that hinder the development of the islands and tourism on them. The subject of this research will be to analyze and explore all the problems, from the need for infrastructure improvement, promoting demographic growth, creating new jobs, and sustainable water and water resource management, in order to define the challenges faced by local authorities and tourism professionals when developing and creating tourism offerings on their islands. Traffic isolation, lack of infrastructure, and water supply issues pose challenges for the islands, affecting both tourists and residents. Tourism can help address demographic issues but requires the involvement of the local population. The EU provides support to the islands through funds, but education on their utilization is crucial. Collaboration with local stakeholders and the population is essential for sustainable tourism development, preserving natural and cultural heritage for future generations. Based on qualitative research involving four participants and analysis of secondary data, it is evident that creating a sustainable tourism offering for the islands of the Zadar archipelago is a complex and individual process for each island. It is crucial to approach these challenges comprehensively, structurally, and sustainably, taking into account the needs of the local population living on the islands throughout the year.
