West Sumatra is a unique and interesting region in terms of geology and tourism. The unique geological aspects of West Sumatra make it have high potential as a geotourism destination. However, the geotourism aspect of West Sumatra has not been assembled into a story in geological perspective so this research aims to study the geological potential of West Sumatra to provide a sequential narrative of the history of landscape formation. This research was conducted in Luak, Lareh and Harau Districts, Lima Puluh Kota Regency, West Sumatra. This research provides several recommendations for geotourism objects and thematic trails for geotourism. The research method used was geosite classification using Kubalikova analysis and the Geological Survey Center's Geological Heritage Resource Assessment Technical Guidelines 2017. The mapping consisted of observations of geomorphology, geology, alignment analysis, river flow patterns, lithology distribution, and geotourism proposals. The method of analyzing the potential of geoheritage consists of geodiversity analysis, geodiversity matrix and quantitative assessment in the Lima Puluh Kota area in 2022 by conducting direct observations in the field and interviews with local residents. Recommendations for geosites and thematic trails were obtained from combining the results of the study with the findings of megalithic era remains by the Medan Archaeological Agency in 2012. The results of the literature study and analysis show that the research area can be divided into five geomorphological units, namely the Limo Puluah Alluvial Plain Unit, the Sago Mountain Foothills Plain Unit, the Barisan Hills Ridge Unit, the Lareh Karst Hills Unit, and the Andaleh Isolated Hills Unit. Geological units in the research area are divided into seven units, namely Quartzite Unit, Shale Unit, Limestone Unit, Conglomerate Unit, Andesite Unit, Tuff Unit, and Alluvial Unit. Based on the analysis of geotourism potential, Luak, Lareh and Harau subdistricts have moderate geological diversity which has a superior theme of Megalithic Cultural Cave Settlements. The highest value is obtained by the Andaleh Area in the form of 293 The author hopes that this research can increase knowledge about geological conditions in West Sumatra. Moreover, this research is expected to help the sustainable development of Luak, Lareh, and Harau sub-districts.
