The development of tourism can badly affect the space of a particular tourist destination if sustainable tourism development is not taken into account when developing tourism products. Tourism implementation is a complex process if it is developed in accordance with the sustainable development of tourism. Due to the complexity itself, many important factors are often neglected in terms of spatial development, conservation of natural and cultural resources, development of communal infrastructure and socio-cultural relations. The development of a tourism product emerges for economic benefits, neglecting the natural resources that are the foundation of the development of the tourist offer of the destination. Sustainable tourism development can greatly benefit the tourist destination itself, the locals and tourists. Research shows that tourists choose those tourist destinations that build their tourism product on sustainable tourism development and those tourist destinations that are more environmentally conscious. Therefore, the subject of this paper is the impact of tourism development on the growth and development of the Municipality of Baška, i.e. the impact of tourism development on the space, the impact of tourism development on the environment, and environmental awareness in tourism development. This paper will explore how the Municipality of Baška deals with the problems of contemporary tourism development in line with sustainable development.
