The Tihi Kanal (Silent Channel) is a maritime passage that connects the Bay of Rijeka with the Vinodol Channel. The channel begins with the passage Mala Vrata and the Vinodol Channel, and runs between the mainland and the island of St. Marco at the western end of the island of Krk, i.e. its mushroom-like peninsula Lanterna. The islet of St. Marco in the middle of the northwest entrance to the channel, divides the channel into the northeast and southwest passage. The large and small arches of the Krk Bridge, connecting the island of Krk with the mainland, rely on the island of Sv. Marko.
The Tihi Kanal is about 3.5-mile long narrow passage between the mainland coast southeast of Cape Oštro and the northeast coast of the island of Krk. On the coast, opposite the lighthouse in the middle of the high, steep and completely bare northeast side of the island of St. Marco, there is the bay Tiha, after which the channel was named, with several quays under the houses. Not far from Tiha Bay there is the cove Uvala Scott with its settlement and below it a thirty meter long stone pier, which is connected to a short quay to the northwest.
