Maubisse is one of the administrative posts of the Ainaro in Timor Leste, which is known to have a very high interest of tourist attractions because of its cold weather and beautiful mountain views. However, those attractive natural phenomena have not been fully used yet as educational attractions (as geotourism). The purpose of this study is to conduct an inventory and interpretation of the geotourism potential in Maubisse, especially in Suco Edi. This research was conducted in three phases: literature study, field research and data analysis of the geotourism potential using quantitative and descriptive methods. The data analysis method used was geosite and geomorphosite assessment based on certain parameters according to Kubalíková (2013). The parameters used were scientific and intrinsic values: education, economy, conservation, and added value possessed by a geosite.
