Tourism activities, which began to attract attention after the “Industrial Revolution”, became more effective particularly after 1950s. After some countries in the world accomplished the process of industrialization, the members of these countries increased the frequency of their journeys around the world. Tourism came to the for front during these years in Turkey like some other countries in the world   The income from tourism is of great importance for the economies of the countries; particularly developing ones; to the extent that they can make a series of serious differences in their economies. Since income level of developing countries is low and their industries are not developed, the income they gain from tourism has a larger share in their general budgets. When the incomes gained from tourism activities are considered, “mass tourism” is the most important one. It can be defined as the type of tourism in which people can reach holiday facilities or as number of people making journeys and having accommodations together and integrating as a holiday group. According to Christaller, the era we are in is the Fifth Tourism which Christaller regards as the turning point for modern tourism.  Mass tourism which has become the most prominent way of earning a living in the south and west coastlines of Turkey has a great many effects in these regions. These effects can be classified as “positive and negative effects” or classified according to the areas they are observed.
