In the last hundred years, the attitude of man towards the environment has changed. The first signs of sustainable tourism development occurred in the second half of the eighteenth century. Four decades ago, the concept of sustainable tourism development began to reflect and how sustainable tourism would affect the future. When planning tourism development policies, it is important to take into account the sustainability of tourism. Sustainable tourism development ensures a sustainable biological system and cultural integrity while meeting aesthetic, social and economic needs. The basic principles of sustainable tourism development are analyzed, as well as their application in the development of a tourist destination. In addition, there are 17 sustainable development goals mentioned. It then discusses sustainable tourism and how sustainable development goals are linked to sustainable tourism. The paper is also dedicated to exploring individuals' attitudes towards sustainable tourism development. The definition of attitude is discussed, how we share individual views, and how these views affect the individual. The paper uses the example of the City of Dubrovnik and, through the views of the local community, seeks to determine whether the existing development of the City of Dubrovnik is going in a sustainable direction. The city of Dubrovnik has been developing mass tourism for years, resulting in damage to the city's infrastructure and urban saturation.
