Chile has a large and intricate coastline of 4000 km with myriads of islands, islets, straits, bays, and fjords.
Moreover, three waterways between the Pacific Ocean and the Atlantic Ocean, namely the Strait of Magellan, the Beagle Channel and the Drake Passage, pass the Chilean coasts. In order to mark dangerous coastlines, hazardous shoals, reefs, and safe entries to harbors, the Chilean authorities maintain 650 lighthouses from the border with Peru to the Atlantic Ocean.
