This type of heritage is very attractive for the cultural tourismsector in general and for active and diving tourism. The Nautical and Underwater Archeology Lineof the University of Cadiz, within the framework of the TIDE Project (Interreg Atlantic Area) andHerakles Project (FEDER-UCA18-107327) have been working on the enhancement of maritime andunderwater heritage through the application of new technologies. In this paper, we will present theadvances in the project in the Strait of Gibraltar, based on the first phase of scientific analysis and onthe definition of a common working methodology that has resulted in a toolkit for the developmentof tourism activities linked to the MCH and UCH. Pilot activities under development are focusedon accessible underwater heritage routes, VR applications to create Dry Dive experiences and thestreaming of underwater archaeological works, thanks to a bottom-surface acoustic communicationbuoy. Results show that these types of outreach solutions and, by extension, of tourism application,must be preceded by a rigorous archaeological research process, a study of the target audienceand the evaluation of the carrying capacity of the sites, to avoid falling into the mercantilisation ordeterioration of the UCH. On the other hand, virtual or indirect access solutions are very useful, butalways through the correct interpretation of the heritage.
