The Lošinj Channel is a sea passage between the southwestern, wooded coast of the islands of Cres and Plitvac Palacol, which consists of numerous dangerous shoals and two islands Oruda and Palacol and the eastern coast of the island of Lošinj from the Osor Strait to the islands of Vela Orjula, Mala Orjula and Trasorka. The eastern coast of the island of Lošinj from the Osor Strait to the southeast is well indented, but many small bays exposed to the storm are not good shelters. The coast to the bay Luka Sv. Jakov is shallow. From this bay towards the southern part of the island the coast is steep with great depths. In front of the central part of the east coast there are two islets: Mali Osir about 0.2 M from the coast and Veli Osir a bit closer to the coast. The southern coast of the island of Cres in the Lošinj Channel is also indented with shallow sea and many bays. The sea passage is extremely important because it represents a shorter route from the Kvarnerić area to the Kvarner area via the Osor Strait in the town of Osor through a dug canal between the islands of Lošinj and Cres. The Lošinj canal is 15 M long.
