To enrich the principle of sustainability through the development of the geographical character of the area along the Palu-Koro Fault as a tourism destination, conservation activities, education, and improvement of the local economy are carried out while still maintaining the carrying capacity of the environment. This study explores the peculiarities of geology, beauty and environmental diversity as potential heritage of Palu-Koro geotourism, so that it is feasible to develop sustainable geotourism in the Palu valley. An exploratory descriptive approach is used to find the formulation of area management from the potential of heritage and geological sites, the need for tourism components, and tourism products. The components studied include Geology and Sustainability. The results show that the condition of the geological sites formed after the 7.4 Richter Scale tectonic earthquake activity is mostly still natural and has not been managed properly. After four years of the disaster, the condition of the Petobo liquefaction area, the post-tsunami coastline, and the Diponegoro fault are all filled with shrubs and liquefaction and tsunami soil deposits, while building fossils still exist.. Therefore, a study is needed that pays attention to the location of the site and post-disaster spatial directions in the Disaster-Prone Zone.
