Kornati is the most dense group of islands in the whole of the Mediterranean. Because of its exceptional landscape beauty, interesting geomorphology, diversity of the coastline and especially because of the rich biocoenoses of the marine ecosystem, greater part of the Kornati maritime zone has been declared a national park in 1980..

The Croatian Kornati archipelago is located in northern Dalmatia, in Sibenik - Knin County,  
between the islands of Žirje, Dugi otok and Pašman. The archipelago is divided into two groups: Lower Kornati consisting of Kornat and surrounding islands and Upper Kornati made of Sit, Žut and surrounding islandsWith 89 islands, islets and reefs, National Park occupies the area of about 220 km2 and is the densest archipelago in the Mediterranean Sea.

A archipelago forming an elongated wall of sheer cliffs facing the open sea, the tallest of which is more than a hundred meters tall. This geo-morphological phenomenon may be experienced almost as a primordial place, since apart from the two small settlements on the largest islet, the remaining islets in the archipelago are uninhabited. The famous Kornati “crowns” (steeps and cliffs) are turned towards open see, and they characterize majority of outlying islands in offshore island series. They are a unique characteristic and value of this area. 

Many of the reefs and cliffs on Kornati are nameless, but some have unusual names: Klobučar, Balun, Košara, Mrtvac. Special feature of National Park Kornati is its numerous old ruins and hill forts, many dating from Illyrian times. It is not only the surface of land and sea which is of interest in this archipelago, but also its underwater world, which is a very popular destination for many divers.
