Sustainable development has an important role in our future and the future of our upcoming generations. In order to tourism to survive, it takes a lot more than "sun and sea". Tourism is, however, a complex branch which included a lot of other activities that allow the development and existence. But with sustainable management, tourism can properly and rationally provide its further existence.Sustainable tourism is based on the reduction of seasonality, to reduce the overload of tourist destinations in certain periods and allow its use for future generations. Many destinations in Croatia, including the Municipality of Pirovac, are faced with the problem of seasonality and the massiveness that can be prevented by the idea of sustainable tourism.
