ا ل م لخ صVirtual reality (VR) is a synthetic, computer-simulated experience that imitates the real world and stimulates the users' visual and auditory senses. With the aid of developed exosomatic instruments and artificial intelligence, VR users may experience a genuine maritime and cultural heritage environment. Virtual diving (VD) refers to the application of virtual reality technology in the context of Underwater Cultural Heritage (UCH). VD allows diver and non-diver tourists to explore the underwater archeological sites, engaging them in an enjoyable experience. Therefore, this study examines how to take advantage of modern technology to promote the Egyptian UCH to be more reachable to large-scale tourism. The Red Sea is one of the most global sites for marine biodiversity. Five maritime and UCH sites in the Red Sea were chosen which are SS Thistlegorm, Wadi el-Jarf,Marsa Gawasis,Saadana Island,and Ain Sokhna. Researchers designed a spatial geodatabase for study sites using Geographic Information Systems (GIS). A qualitative methodology approach was adopted through semi-structured interviews with managers and experts in some official institutions responsible for managing the Egyptian UCH. Results revealed that VR and VD technologies can be applied in particular sites compared to others due to some practical considerations such as water condition, accessibility, the possibility of monitoring the site, and the risk of heritage destruction. Experts have shown great interest in VR and VD, asserting that UCH in the Red Sea necessitates innovative marketing strategies. Eventually, some suggestions for exploiting VR and VD were proposed for managers and policymakers to promote the Egyptian maritime and UCH.
