In the fields of geology, economics, history, cultural studies, and ecology, tourism can be the basis for proper planning, for sustainable tourism management, and for economic development. The Dasht-e Lut is one of the most significant desert areas in Iran due to its exemplary desert patterns and world-famous landscapes, such as the kaluts and nebkhas landforms. Furthermore, it is the hottest spot in the world and can attract adventurous tourists, amongst others, from around the globe. The purpose of this study was to determine and compare the most suitable geomorphosites for better sustainable tourism planning using three methods of evaluating geotourism as proposed by Pereira et al., Pralong, and Reynard et al. The results show that the geomorphosites of kaluts, nebkhas, and Gandom Beryan had the greatest potential for different reasons. In addition to geosites and geomorphosites, the night sky was also demonstrated to have a high potential to attract tourists. Using the economic criteria of the Reynard method, all geomorphosites had similar scores. The familiarity of officials and tourism planners with the tourist capabilities of this region can lead to economic and cultural capacity building for the Indigenous people and the tourism industry.

The attractions and capabilities of geomorphosites are among the unique assets of each country, and their identification, classification, and planning have great importance for the development of tourism. The purpose of this research was to identify, quantitatively analyse, and classify landforms treated as geosites and landscapes of Yazd Province, using the Pralong method. The present study is a descriptive analytical research based on library studies and field surveys. After determining the study area using satellite imagery, six geomorphosites were selected. Using the Pralong method, six geomorphosites were evaluated: Chak Chak, Mountain Eagle, Siahkooh, Shirkooh, Qanat, and Barfkhane Tezerjan. In this method, using the extraction of collected data from the questionnaires completed by 41 geotourism experts in the first stage, the four grades that were evaluated in terms of potential capability of geomorphosites include the appearance aesthetic, scientific, historical-cultural, and socio-economic variables, and in the next step, two variables of productivity value and quality of productivity were evaluated. The results of evaluations showed that the geomorphosites Chak Chak and Barfkhane Tezerjan had the highest score (0.62) and are the best geomorphosites for converting to geotourism and ecotourism applications, and they have high potential for attracting tourists. The second place was dedicated to the Shirkooh geomorphosite, which is considerable in terms of the average tourism grade. The best average productivity value belonged to the Chak Chak geomorphosite with 0.52, and the last one was Mountain Eagle with 0.32. All six attractions in this study had a medium grade in the qualitative scale index, meaning that they have good potential in geotouristic and ecotouristic points of view and could be improved by regional planning. Therefore, the results of this study can be used by local managers and planners to develop and promote geotourism and ecotourism.
