Geotourism is sustainable tourism form which is primarily based on the existence of geoheritage. Many research studies have been devoted to assessing geoheritage in last two decades, from various perspectives. Depending on the assessment methods and results, authors of such studies often refer to potential geotourism development based on specific geoheritage values. This paper, based on a study and analysis of relevant literature retrieved from WoS and Scopus databases, focuses on assessment criteria and their relevance to geotourism development for the general public. The results show that the absolute majority of assessment methods are probably of high importance for experts. However, in terms of effective application of the assessment results to sustainable geotourism development, different criteria should be used, including visual attractiveness, uniqueness, accessibility, safety, and the possibility of gaining knowledge. In this regard, extensive research is required on how geoheritage and its interpretation appeal to visitors, especially among the lay public.
