Similar legends are probably told about other archipelagoes and groups of islands, but there is no doubt that in the case of the Kornati the legend is fully justified. The most valuable geomorphologic and scenic features of the National Park, including the seabed, are to be found in the last series of Donji Kornati facing the open sea. This series contributes most to the idea of indentedness being associated with the Kornati. It is here, facing the open sea, that we find the impressive cliffs and crags.
Cliffs result from the combined action of several factors.
Geologists tell us that this series of islands represents the remains of the northeastern part of the interrupted anticline which is continued in Dugi Otok. The great indentedness and the cliffs are not the only interesting features in the landscape of the National Park. The southeastern tip of the main island is 7 km long and only 200 - 300 m wide. A much smaller island, Katina, is squeezed between Kornat and Dugi Otok, separated from both by the narrow and shallow passages of Mala and Vela Proversa. These were made into maritime passages by the Romans, who deepened them to about two meters, so that smaller craft could pass through them.
