Strait of Magellan

The Strait of Magellan is a navigable sea route immediately south of mainland Chile, South America and north of Isla Grande de Tierra del Fuego. The strait is the most important natural passage between the Pacific and the Atlantic oceans, but it is considered a difficult route to navigate because of the inhospitable climate and the narrowness of the passage. It is about 4 km (2½ miles) wide at its narrowest point.
