The Krong No volcanic caves at the Dak Nong UNESCO Global Geopark (Dak Nong UGGp) were discovered in 2007. Between 2017 and the present, they were comprehensively studied and evaluated for heritage value from the perspectives of geology, biology and cultural studies. These primitive, endogenic caves are characterized by rich and diverse interior formations, representing seven types of geological heritage as classified by the UNESCO and its GILGES classification system. The applicable types are A (Paleontology), B (Geomorphology), C (Paleo-Environment), D (Rock), E (Stratigraphy), F (Minerals), and I (Tectonics). The cave system’s wildlife is highly diverse and includes a number of newly discovered species endemic to Krong No. Thanks to research and excavation work, many types of archaeological artifacts have been discovered in the Krong No volcanic caves, including relics of residence, a tool-making site, burial artifacts, a makeshift hunting camp, and some artifacts possibly expressive of religious ritual. All of these are unique, valuable and rare. The various types of heritage discovered in the Krong No volcanic caves constitute the premise of an on-site conservation museum, established to promote heritage of value, teaching and scholarship, as well as community education and recreation. This article introduces a new direction for further research, related to the development of an on-site conservation museum of the volcanic cave heritage in the context of sustainable socio-economic development.
