This study explores the sustainable management and valorization potential of Crvena Stijena, a prehistoric archaeological and geosite in Montenegro, renowned for its scientific and aesthetic significance. The research highlights Crvena Stijena’s unique archaeological depth, offering insights into Neanderthal subsistence strategies and environmental adaptations, positioning it as a significant site for both archaeotourism and geotourism. However, current limitations, including inadequate infrastructure, insufficient promotional materials, and a lack of interpretive resources, restrict its accessibility and attractiveness. This paper evaluates the site’s potential for sustainable tourism development, analyzing visitor motivations and behaviors and the role of geodiversity and arheodiversity in heritage conservation. The study provides targeted recommendations for enhancing the visitor experience through infrastructure improvements, interpretive signage, and community involvement, while emphasizing conservation measures to preserve Crvena Stijena’s geological and cultural integrity. Additionally, it includes a SWOT and PESTEL analysis to guide policy makers, conservators, and academic institutions in developing a collaborative approach to the site’s management. By integrating these strategies, Crvena Stijena can evolve as a model of sustainable heritage tourism, benefiting Montenegro’s cultural tourism sector and fostering appreciation for its prehistoric legacy.
