Comments and Feedback
The National Marine park of Alonissos and Northern Sporades is the nature reserve for a series of terrestrial and marine species living in the Mediterranean Sea, including hundreds of plants and animals, as well as remarkable archaeological and historical monuments. From both a scientific and a cultural point of view, this is an area of great interest given the archaeological finds (shipwrecks, old monasteries and churches) dating back to the prehistoric era, the classical period or the Byzantine Empire. Visitors are welcome to enjoy swimming and diving, take pictures, record videos, go sightseeing, walk around or observe the wildlife in areas where public access is permitted. There are also specific marine areas where fishing is allowed for amateur fishermen. Peristera is an uninhabited island spread with macchia vegetation. Underwater archaeological research has brought to light an old shipwreck along with a series of other archaeological finds revealing that Sporades Islands had always been an important sea route for ancient cultures. Therefore, one of the primary goals set by the National Marine Park consists in preserving these archaeological finds and making them known to the world in cooperation with local authorities.
