Geographically, it is an island of great diversity and contrast, and the largest island among the North Dalmatian islands. It justifies its name (long island) with a length of about 45 km and it is between 1 and 4 km wide, with the highest peak Vela Straža (338 m). The coast of the island facing the open sea is characterized by sharp contrasts: the part that is located in the Nature Park is mostly steep and dominated by beautiful cliffs, while on the southeast side of the island one can find quiet coves and the sandy beach Sakarun. The island's beauty is an ideal place for swimming and enjoying the purity of the sea and the beauty of nature.
As the south-eastern part of the island is protected and declared a Nature Park, so is the north-western part of the island recognized as one of the most interesting areas of the Zadar County and was declared a significant Croatian landscape.
