Some of the geological occurrences during the past can be viewed very imposingly through the Kornati “crowns”. Vertical cliffs of the Kornati islands facing the open sea are the most popular phenomenon of this park. The "crowns" represent a large tectonic fault surface that extends from the Istrian peninsula and ends somewhere in the middle of Dalmatia (maybe even southern), and it was caused by a global movement of Africa to the north and its "driving" into Europe.
The longest “crown” above the sealevel is situated on the island of Mana (1350 m) and the highest on the island of Klobucar (82 m). The “crowns” strech under the sea, too. The deepest “crown” is situated on the island of Piskera (over 90m).
The “crowns” are homes for some very brave organisms: peregrine falcon, coemorant, swift, plant community of Centaurea ragusina.
