Geomorphotourism is one of the tourism branches base on nature which have high potentials for tourism planning by combining ecological, historical and cultural inheritances. In the other words, geomorphotourism introducing the geomorphological landforms to tourists by keeping the local identity. In this relation, this research tries to study the tourism capabilities of Sirjan geotops using Fassoulas and Comanescu models. The used values in Fassoulas model consist of scientific, ecological and protective, cultural, aesthetics, economical and utilization potential values and in Comanescu model consist of management, yield economic, cultural, aesthetics and scientific values , that each of these values have some sub-standard that have been determined from 1 to 10 for Fassoulas model and 20 for Comanescu model by standard score system. The results of this research indicate that geotop of Sirjan salt desert with 18.8 score in Fassoulas model and 0.78 in Comanescu model have the maximum score for tourism development. Also, according to results, the troglodytic geotop with 12.2 score in Fassoulas model and 0.34 in Comanescu model , have the minimum score among studied geotops. According to research results, the maximum score of Sirjan desert geotop relate to scientific value and aesthetic and suitable access this salt desert.
