Augmented Reality (AR) represents a significant technological advancement in the fields of museum interpretation and cultural heritage tourism. By overlaying digital information—such as 3D models, text, audio, and interactive animations—onto real-world artefacts and heritage sites, AR enhances visitor engagement, accessibility, and learning outcomes. This research examines the role of AR in museum and heritage tourism, focusing on user experience, educational value, authenticity, technological adoption, and management challenges. Using mixed-method data (survey of 430 visitors, interviews with 20 curators, and analysis of 12 AR heritage projects), findings show that AR improves immersive learning, emotional engagement, and visitor satisfaction while supporting heritage conservation. However, concerns persist regarding cost, technological barriers, digital distraction, and issues of cultural authenticity. This study presents a comprehensive model for AR adoption and concludes with recommendations for heritage institutions seeking to integrate AR effectively.
