The inherent link between the mining history and culture in the region of Banská Štiavnica (Slovakia) and the unique geological and morphological heritage offers significant potential for the development of geotourism and educational trails, thus presenting the heritage to a wide spectrum of visitors. In recent years, online availability of information about such trails has become very important for the digital society that uses the internet and social networks daily. This article focuses on the development and online information availability of geotrails located in the territory of the first Slovak geopark, Banská Štiavnica Geopark. Results show that there are very few geoscience-based trails with limited online information available. By investing in effective on-site heritage interpretation and proper online promotion, the territory can become a premier geotourism destination.
