With urbanism and city development, the natural environments around cities change and lose their natural character. These natural landscapes, affected by city development and overuse for recreational purposes, gradually become destroyed. The main objective of this research is to preserve the natural landscapes near large cities, both to limit the city boundary and to create ecotourism sites with less interference in nature and creating the potential for people to enjoy and relax from these beautiful natural scenes. The Alborz hills are one of the natural resources in the north of Tehran. These highlands can provide many environmental and recreational services. District one of Tehran municipality is one of the northern areas of Tehran which has a rich potential for tourism and ecotourism sites. In this research, the foothills between Darabad valley and Jamshidieh Park were selected as forming part of a natural zone near Tehran which is affected by city growth as a case study. Then by using maps, aerial photography, satellite images and field visits, two walking trails were defined and located on the map. Finally four sites (stations) along these trails proposed and designed based on environmental studies such as topography, vegetation cover, water resources, erosion and landscape analysis.
