At the southern end of the National Park’s protected area lies the wetland of the Lagoon of the Alyki Kitrous. This region extends over approximately 15,000 hectares, including the lagoon of Kitros, with its salt production unit, as well as the wetlands extending to its south, and reaching Korinos.

This whole region is particularly valuable as to the biodiversity it hosts and mainly as to the avifauna, the herpetofauna and the shore birds that are fed there, spend the winter there and are reproduced as well as species of flora to be found there, thanks to its great diversity of habitats. These habitats range from the shallow lagoon waters, to its southern salty water marshes, the coastal scrubland and the sand dunes flanking the coastal zone.

The region belongs to the Natura 2000 network as the “ALYKES KITROUS – BROADER REGION” Special Preservation Zone.
