The basic organisation of the National Park consists in establishing a graded system of protection zones (4 zones in total), each one with its own protection level and special regulations.
The first two zones (Zone Ι: Nature Protection Areas and Zone ΙΙ: Landscape, Habitats and Species Preservation Areas) are characterized by a higher protection than the Zone ΙΙΙ (National Park Area) and the Peripheral Zone (Zone IV), where the protection is lower.
The protection zones of the National Park and the areas they occupy are listed in the following table:
