A total of 16 % of surface area of the Adriatic islands, exactly 513 km², belongs to the islands of Cres and Lošinj which is 99 km long and stretches from northwest to southeast. The island of Lošinj (75 km²), is an integral part of the Cres-Lošinj islands and together with the island of Cres (409 km²), Ilovik (6 km²), Unije (17 km²), Susak (4 km²), and Vele Srakane (1 km²), as well as many small uninhabited islets, forms the western stretch of the Kvarner islands in the eponymous bay. Their position serves as a natural bridge between Dalmatia and Istria. Along with the Gulf of Trieste, this is the deepest indented part of the Mediterranean into the European continent.
The islands of Cres and Lošinj, passing the 45th northern parallel, are situated in the middle of the northern hemisphere, more precisely in the subtropical zone of the southern half of the northern hemisphere, which greatly affects the climate and local life.
Island of Lošinj is the 11th biggest island in the Adriatic, and it is up to 4.75 km across in certain areas, whereas the narrowest part is only 0.25 km across near the town of Mali Lošinj. Its coast is suitable for swimming and sunbathing with plenty of inviting coves and lagoons. The island is 33 km long, and the length of its indented coast stretches to staggering 112.7 km.
Osoršćica, the island’s highest peak (588 m high and 10 km long), stretches along the northern part of the island of Lošinj. The biggest mountain on the island of Cres is Sis (650 m) that is complemented by a natural phenomenon – the Lake Vrana. This freshwater lake contains 200 million m³ of potable water that supplies all settlements on the islands of Cres and Lošinj.
Long time ago, Cres and Lošinj formed a single island, however, an artificial channel near Osor was dug in the Roman period, splitting them in two. They are still considered a single island with regards to the geography and transport connections.
