This study is about the geology and geosite potential of karsts in Kampung Batu Udang, Dabong District, Kelantan by using the Modified Geosites Assessment Model (M-GAM). The purpose of this study is to update the geological map of Kampung Batu Udang at Dabong with a scale of 1:25,000 based on interpretation and to give exposure to the uniqueness of karst features at Kampung Batu Udang located in the Dabong District of Kelantan that is known for its karst formations. The area is situated in the eastern portion of the country and is known for its unique limestone formations and caves. The geology of the area is primarily composed of Paleozoic and Mesozoic rocks, including sandstones, shales, and limestones. The limestone formations in the area are believed to be of Late Permian to Early Triassic age. The study area contains unique karst geomorphology and geomorphological structure to conduct research and surveys. The M-GAM is a tool used to evaluate geosites and includes both main values (MV) and additional values (AV) based on the Geosite Assessment Model (GAM). It considers the views of two different groups, which can affect the final assessment of the geosite. The study area's geological map has been updated, and the M-GAM assessment of high values indicates the suitability of geosite potential with a high-value indicator of scenic and aesthetic for MV and for AV was touristic values. This is because these values are seen as important to visitors who are looking for attractive and visually pleasing landscapes, as well as opportunities for recreation and tourism activities. The high score for these values shows that the study area may have a strong potential for development as a geosite, attracting visitors and potentially boosting local economies. These results suggest that the area has the potential to attract tourists and visitors due to its unique and visually appealing geomorphological features
