Tourism being one of the greatest and fastest growing industries of the world is contributing significantly to the development of countries and the host communities. But this industry is facing many problems in most of the developing countries including Pakistan. Most of the issues are raised due to lack of planning which not only dissatisfies the tourists but also has negative impacts on the local communities. Unplanned tourism not only affects the host guest relationship but also the tourism resources of an area. The study in hand is author’s part of PhD research and highlights the problems of host regions caused by tourism in Pakistan, taking Kaghan valley as case study. The results of the study show that if proper measures are not taken well in time, the unplanned tourism will destroy the natural and socio-cultural environment of the valley very soon.
