The tourism industry is experiencing a profound transformation driven by digital innovations such as virtual reality (VR), augmented reality (AR), and interactive platforms. This paper explores how these technologies are reshaping destination competitiveness, with a specific focus on the mining heritage sites (MHSs). By leveraging VR and AR, heritage sites can offer immersive and interactive experiences that enhance visitor engagement, and broaden their reach. Through a case-study analysis, this work examines successful implementations of digital tourism initiatives at various MHSs including the Big Pit National Coal Museum, the Mining Museum of Slovenia, the Mining Museum of the West, the Erzgebirge Mining Region, and the Mesabi Iron Ore Mines. The findings reveal that digital tools significantly improve accessibility, educational value, and global appeal of these sites. However, challenges such as the technical and financial constraints remain. The paper concludes with recommendations for practitioners on integrating digital technologies effectively and suggestions for future research to explore long-term impacts and emerging trends. This work underscores the transformative potential of digital innovation in enhancing the competitiveness and sustainability of tourism destinations.
