In a natural park, tourism is seen as an economic activity that can easily bring many benefits. Apuseni Natural Park (ANP)was chosen as a case study because it impacts communities (and especially moți) which have preserved their culture and traditions, coming from ancient times, in an area with remarkable natural and anthropogenic tourist resources. The aim of the study is to analyse the perception of local communities (endogenous), and visitors (exogenous), in order to highlight the heritage, economic advantages, and constraints in the natural park. The research is based on survey method and a number of spatial analysis tools, GIS, bibliographic sources, cartographic data mining, and field observations. The results show that local communities perceive in a high ratio the advantages of heritage preservation, linking them to the improvement of their life and less the disadvantages on the local economy. A more significant contrast in perception is revealed by tourists, who think that a national park has many advantages and constraints, the last ones accounting for the possible loss of functioning of the destination. In the frame of the recognised attractiveness of the ANP, the study suggests the need for a continuous monitoring process and the adoption of a receptive administration for each area and every actor involved.
