Kornati National Park
The Kornati archipelago of Croatia, also known as the Stomorski islands, is located in the northern part of Dalmatia, south from Zadar and west from Šibenik, in the Šibenik-Knin county. With 35 km length and 140 islands, some large, some small, in a sea area of about 320 square km, the Kornati are the densest archipelago in the Mediterranean Sea. From northwest to southeast (from the island of Balabra to Samograd), and from northeast to southwest (from Gangarol to Mana) they stretch for 13 km (8 miles). The name of the archipelago is the plural form of the name of the largest island, called Kornat.
