Tourism development in destination areas is often associated with negative environmental impacts if its management is, poor as environmental damage arises if the number of tourists is large or the resource is overused. Overcrowding, misuse of natural resources, the construction of buildings and infrastructure, and other activities associated with tourism produce impacts on the environment. According to Ceballo-Lascurain (1996), in protected areas, tourism impacts are either direct or indirect.
