A geopark is the best place for scientific knowledge dissemination, recreation and regional economic development. However, research on science tourism in China’s national geoparks is still in its infancy and the theory is lagging behind practical development needs. For the purpose of exploring the shortcomings and optimization paths of geoparks in science tourism development, here, we used Koktokay World Geopark as the research object and examined the internal advantages, internal disadvantages, external opportunities and external challenges. Then, using 17 indicators, such as natural resource endowment, a SWOT-AHP model was constructed to systematically analyze the advantages, disadvantages, opportunities and threats. The analysis found that advantages > disadvantages > opportunities > threats. The SWOT four-quadrant strategy was positioned at the first quadrant, and the advantage–opportunity strategy should be based on its internal advantages and make full use of the external opportunity conditions. Based on the results, suggestions were made to maintain resource advantages, obtain policy opportunities and improve the transportation conditions and the interpretation system; hence, in this study, a reasonable path for the development of science tourism in Koktokay World Geopark was explored and theoretical references for the science tourism and sustainable development of other geoparks were provided.
