The evaluation of carrying capacity is applied to demonstrate the impact of tourism on space and the envi­ronment. It shows a significant element of planning spatial growth in tourism. It is also one of the techniques used to establish standards for sustainable tourism. Essentially, carrying capacity of a destination is the maximum number of tourists that can stay in a tourism destination and utilize its resources in a manner that does not cause intolerable and irretrievable alteration in the structure of the destination. The structure of the destination is defined in terms of its environmental, social, economic and cultural characteristics. The carrying capacity does not decrease the quality of destination in terms of tourist’s experience. Available research depicts that many researchers and institutions have studied the challenges concerning the carrying capacity of tourist destinations. Carrying capacity has been defined as the ability of an ecological unit to sustain and activate the growth of human activities adequately without negative impacts or consequences (FNNPE 1993, p.2). Three levels that are important for evaluation of carrying capacity have been identified. These include socio-cultur­al, ecological and psychological (WTO 1997, p.1). A lot of studies on carrying capacity have been carried out in theoretical approach to the idea. This implies that the practical application some of these perceptions encounter a lot of challenges (Mitchell 1989, p.20). It is a common belief that the conception of carrying capacity is by itself significant and functional. However, previous research has indicated that in daily practice it has been repeatedly neglected and replaced with other theories. Some concepts that have replaced carrying capacity include limited tolerable change in the tourism destination and techniques of tourist management (O’Reilly 1986, p.5). Carrying capacity ought to include natural environment and changed human factors in addition to its practical application. A dominant relationship has been found to exist between the natural environments and the carrying capacity. The concept is characteristically an elusive subject that is still to be studied. Considering the challenge of sustainable growth, it is important to note that tourism causes various negative impacts that may risk long-term growth. Carrying capacity is a significant structure for identifying and understanding notable challenges (O’Reilly 1986, p.7). Nevertheless, some studies are against this view; it has been suggested the application of alternative and more flexible framework. Some studies disagree with the interdependence between the concept of carrying capacity and the definition of sustainability of tourism growth. These studies assert that if sustainable growth means respecting for the requirements of the present generation while protecting the requirements of subsequent generations then, instead of carrying capacity, the emphasis should be given to definition of the limits for the utilization of tourism destination before a major deterioration in the quality of tourism resources (Butler 1999, p13). The enduring discussion on the conception of carrying capacity has focused to the necessity for comprehensible an
