The topic of this final paper is to analyse and investigate the potential for the development of special forms of tourism in Brijuni National Park. The purpose of the paper is also to explore the potential for the development of special forms of tourism in the protected area, and the aim of the paper is to elaborate special forms of tourism that have the greatest potential for development and how they contribute to the sustainability of tourism and the overall image of the Brijuni islands. The research confirmed the initial hypothesis that special forms of tourism represent a sustainable form of tourism development for the National Park Brijuni as well. The author also conducted research on a new type of selective tourism – asro-tourism for which the Brijuni have predispositions. It was concluded that the proclamation of Brijuni as a dark park would lead to a serious turning point, and people would become aware of the importance of preserving the dark sky and Brijuni would be the first Croatian island on the Adriatic to have such status, which would further contribute to a great advantage over other tourist destinations of the Adriatic.
