The Natural Park “de ses Salines” of Ibiza and Formentera is a great example of the richness and diversity of the flora and fauna in the Mediterranean area. It is a place of tranquility and provides nesting grounds for various species of birds on their migrations. This natural park is particularly interesting and includes habitats on land as well as in water. Therefore it is of great ecological, scenic, historic and cultural significance. On the 4th of December 1999, it was declared as World Heritage site by the UNESCO, which puts the whole park under special protection because of its huge ecological value.
