Southernmost of all big Croatian Islands, according to the legend, the place where Homer’s nymph Calypso used to live. The west third of Mljet was declared national park in 1960. Key reasons for that were well-indented coast and very rich original forest land cover. The largest part of the forested areas consist of autochthonous forests of pine, and the most significant species is the one of holm oak („crnika“ or „česvina“).
The green and mystical island of Mljet is one of the larger of the southern Dalmatian islands, with one third of it – in the Western part – enjoying the status of a national park.
In the most thicly wooded part of the coast facing the open sea, the sea has retracted deep into the land, creating the most famous phenomena of the park- The Great and the Small Lake. In the middle of The Great Lake, there is the islet St. Mary with the Benedictine monastery and the church, dating from the 12th century. Rich fauna on Mljet has not been completely explored yet. Beside numerous amphibians, reptiles, birds, and mammals, on the side of the island facing the open sea, extremely rear species of Croatian fauna lives – Mediterranean monk seal.
