The Beagle Channel is a strait separating islands of the Tierra del Fuego Archipelago, in extreme southern South America.[1] It separates Isla Grande de Tierra del Fuego from the islands Nueva, Picton, Navarino, Hoste, Londonderry, Stewart Islands and other smaller to the south. Its eastern portion is part of the border between Chile and Argentina, but the western part is completely within Chile. The west end is the Darwin Sound and the east end is Nueva Island.
The Beagle Channel is about 150 miles (240 km) long and is about three miles (5 km) wide at its narrowest point. To the west the Darwin Sound connects it to the Pacific Ocean. The biggest settlement on the channel is Ushuaia in Argentina followed by Puerto Williams in Chile, two of the southernmost settlements of the world.
