Many are the projects to enhance Underwater Archeological Heritage, from wrecks to villas to port structures. Coastal Management is a subject itself which every day more involves archaeological studies in long term territorial planning (Daire 2014).  In the Olbia Gulf a technical preliminary study for an Underwater Archaological Park was done in the 90’ by the Soprintendenza (SABAP SS NU OT Archive) when also the underwater park of Ustica was born (Purpura 1992) but then the park was never realized because of protection issues. In 2001 the Tavolara Punta Coda Cavallo Marine Protected Area (then cited as AMP Tavolara PCC) was established, then endowed with a management plan and a regulation by 2007 but the archaeological enhancement of the many underwater sites preserved (which notice was given in the national Bollettino di Archeologia: D’Oriano-Riccardi 1990-1991-1993-1997) is still not possible because of the not yet exceeded protection requirements.  The study presented in this poster was lead during a University course of Marketing and Management of Cultural Heritage, and is centered to focus the statement of the problem in 2018 through stakeholders perception of underwater archeological heritage in the AMP Tavolara PCC and its value also for tourism. Stakeholders are individuated following the indication in the Management Plan of the AMP as published in Del Principe-Nicolini 2008, and the questions of the survey administrated to them follow the Mires 2014 phd doctoral study, the UNWTO 2018 and Gray 1985.  A conclusive reflection is given confuting Hannahs (2003) following statement: ‘If the best use of a resource is to be made through public access and not through an archaeological recovery of information, should archaeologists be taking the lead in managing these resources? If the value o f a cultural resource resides in its archaeological potential, then increasing the stress on that resource by encouraging public visitation is a bad idea. If the value of a cultural resource is not primarily archaeological, why are archaeologists taking the lead role in management decisions concerning them?’
