Situated on the island of the same name, Mljet National Park is the most important protected area of the Dalmatian south. It is the oldest National Park at the Adriatic. The park covers the western part of the island, which many regard as the most alluring in the Adriatic, full of lush and varied Mediterranean vegetation. The park includes two deep bays which, due to their extremely narrow links with the sea, are regarded as and indeed named lakes: the Great Lake and the Small Lake
