Gunung Sewu UNESCO Global Geopark (UGG) will be reassessed by UNESCO based on the criteria geopark set by UNESCO in 2019. This research was conducted to evaluate one of the components of geopark UGG Gunung Sewu, namely Gunung Api Purba Nglanggeran Geosite located in Nglanggeran, Patuk, Gunungkidul, Daerah Istimewa Yogyakarta, from geotourism point of view and some criteria of geopark that established by UNESCO. This research is also conducted to present some recommendation of new geotourism object for Gunung Sewu UGG development especially in Gunungkidul, Daerah Istimewa Yogyakarta. The research method used in this research are divided into two, the method of geological field observation and geotourism questionnaire method on Geosite Gunung Api Purba Nglanggeran. Geological field observation method consists of geomorphology observation, geological structure observation, and lithologies observation in research area. Geotourism questionnaire method consists of questions and assessment of Geosite Gunung Api Purba Nglanggeran based on criteria geopark established by UNESCO with questionnaires respondents from geosite tourists and residents around the geosite of Gunung Api Purba Nglanggeran. Geotourism objects Recommendation obtained from further analysis of field observation methods. Based on that above methods, the research area is divided into four geomorphology units, namely Nglanggeran Homoclinal Ridge, Sambipitu Denudational Plain,Wonosari Hills of Karst, and Oyo Flood Plain. The units of lithologies in the research area are divided into four, namely Tuff-Sandstone Unit, Piroclastic Breccia Unit, Sandstone-Claystone Unit and Limestone Unit. The geological structure that developed in the research area are Ngalang Strike-Slip Left-Lateral Fault, the Bunder Strike-Slip Left-Lateral Fault, and the Beji Strike- Slip Left-Lateral Fault. From the results of questionnaires analysis, Gunung Api Purba Nglanggeran is still considered to preserve the criteria geopark set by UNESCO. Based on the results of geological field observation analysis, some recommendations of geotourism object are Air Terjun Kedung Kandang, Bukit Kembang, Gunung Gentong, Kali Ngalang (hulu), and Batu Miring Oyo.
