It is commonly accepted that tourism is the backbone of economic development of Greece. As a form of economic activity, tourism falls in services, which means that special attention is given the infrastructures existing in the quality of services. In Greece in recent years an effort to upgrade the tourism product has been made through the up grading of services but also a shift from the model of mass tourism that prevailed in previous decades, to the model of sustainable tourism. The reason leading to this shift has to do with international trends in tourism and with the fact that Greece offer s a unique 'puzzle' tourism resources are not limited to 3S (Sun, sand, sea) of mass tourism but can offer unique experiences in both summer and winter tourism. This paper has revealed that despite of the fact that sustainable tourism is accepted as a key mean of development, there are some issues such as with planning and implementation along with some wrong perceptions from the side of the entrepreneurs.
