Sustainable development is of the most importance not only for tourism, but also for the entire community. It represents a concern for the environment, economy and society, in a way that natural resources are consumed as effectively as possible. In recent years, the man is increasingly becoming aware of the fact that he needs to live healthy and environmentally friendly. This way of life is carried on to tourism, so destinations that care about sustainable development are becoming more valued. In the world today sustainable tourism is a determinant essential for the general development of tourism and enhancement of economic development. In the context of sustainable tourism, tour operators can have a significant impact on its improvement. As a direct intermediary between the destination itself and tourists, they can create tour packages that are based on the principles of sustainable tourism. These tour packages are organized in less known destinations, and require close contact with the local population in the destination. Tour operators that type of packages organize for smaller groups of tourists, often doing business with local hotels and in that way contributing to sustainable development in the area. In order to make tourism sustainable, in such development almost all of the participants should be included, from the local community, population, tourists to travel intermediaries and agencies that bring tourists.
