Example of best practice : Portugal
Subaquatic Archaeological Charter of the Azores, Portugal
The Azores archipelago counts over one thousand registered shipwrecks, submerged in over five centuries since people first arrived to live on the islands. The Regional Government selected 30 UCH sites for a subaquatic itinerary to allow reasonable access for visitors. In terms of efforts for a responsible access to the public, the Regional Government implements a series of touring exhibits on underwater archaeology and develops educational and interactive material for the general public. . .

Restricted heritage access to the main sites are now offered to the public. Some sites that remain under study but generate extra interest have been made accessible to amateur divers, provided that the visits can be integrated into the monitoring work of archaeologists and biologists. . .
