Kornati National Park was established in 1980, spread over 220 km² it includes 89 islands, islets and rocks, covering approximately 238km of coastline. Three-quarters of the park is underwater marine ecosystem, the best way to tour it is on a cruise ship.

The mainland portion of the park is privately owned and has for centuries been used for grazing animals and planting olive trees. The division of land is marked by centuries old stone walls which are one of the symbols of Kornati, but are also a reminder that during your stay on the islands you should behave as good and considerate guest.

Unique geological origin of the islands is evident in the phenomenon known as "Krune" (the crown). Islands tall vertical cliffs facing the open sea are the surface of a large tectonic fault that was created in the collision of African and Eurasian tectonic plates. "Krune" are a favorite spawning place for rare birds, home to many plants, but with some of them more then 80 m high they also offer unforgettable views to many visitors. Longest "kruna" is 1350 m long, and the deepest one goes over 90 m below sea level.

The underwater world of the Kornati National Park is well worth exploring. Swimming and snorkeling does not require a permit, but a diving tours are only allowed in organized groups.
