Ecological routes should have social, cultural and educational scientific functions. In order to make full use of their potential, the work should be done for studying the conditions of the areas where the routes are located or planned to locate. It is advisable to start researches in nature reserves with ecological routes, where access to the territory of reserves is limited by ecological routes. This paper presents the results of the study of geoenvironmental conditions of the Karadag natural reserve along the ecological route. Along it the main rocks, relief, vegetation, projective covering and its safety, surface inclination are studied and absolute marks of height of a relief are measured. Based on the results of the research, the conclusion was made that according to the sum of geoenvironmental parameters and the degree of anthropogenic disturbance, the route and the adjacent territory consist of five different geoenvironmental sites. © SGEM2019.
