The Vinodol Channel is a sea passage that stretches in the northwest-southeast direction. On the northwest side it continues into the channel Tihi Kanal and on the southeast into the Velebit Channel. On the eastern mainland, the channel stretches from Cape Ertak near Jadranovo in the northwest, then in a southeasterly direction to the bay Žrnovnica near Klenovica, and on the western side it stretches along the northeastern coast of the island of Krk from Cape Bejavec to Cape Glavina. The coast of the island of Krk towards the channel is steep and without vegetation, just like the coast south of Novi Vinodolski. The length of the Vinodol Channel is 18 km and the channel is the narrowest at the very beginning in the northwest at Cape Ertak and in the area between Crikvenica and Šilo (island of Krk) where the width of the channel is slightly more than 1 M.
The Vinodol Channel is to the north of the Velebit Channel, and then continues into the channel Tihi Kanal, between the mainland from Cape Ertak to bay Žrnovnica and the northeastern coast of the island of Krk from Cape Bejavec to Cape Glavina. The slopes of the mountain range along the coast in the northern part of the Velebit Channel, in the area of the Vinodol Channel, gradually descend to the coast, mostly overgrown with forest and partly cultivated. From the port of Novi Vinodolski, the coast becomes steep, without vegetation and the depths along the coast are great.
