While visiting the island, you can admire an open-air museum of natural history in West Milos: Mountain tops, isolated coasts, rare flora and fauna, migratory birds and in general a region of incomparable beauty, intact from human destructive interventions.

Achivadolimni, the biggest natural wetland in the Cycladic islands, a main home for migratory birds, the blackrobin, a rare migratory hawk, other kinds of birds such as Bitterns, Limoges, Marsh Harriers, Whiskered Terns, Ospreys and Ortolans, the Mediterranean seal which lives in the wider region of Milos, the forest of cypresses with the horizontal branches including perennial trees of a great value in aesthetics and flora, one of the most rare species of our planet: the red viper Vipera Lebetina or Microvipera Schweizeri, the rare wild goat species of Antimilos, as well as the rare flora in these regions make Milos a unique place.

The land and coastal zone in the west part of Milos belongs to the region network of NATURA 2000 of the European Union. These regions thanks to their rare characteristics are armed as being “Places of Communal Importance” and they are legislated as “Special Reservation Zones” so as to prevent the natural balance and  the biodiversity of their ecosystems, as well as to protect their rare flora and fauna.

Particularly, the wider region of Prophitis Ilias (code: GR4220020), Antimilos and the coastal zone of the island’s west part (code: GR4220007), and also the island of Polygaios (code: GR4220006) are regions protected under their accession into the NATURA network so that their natural heritage be preserved intact.
