Cape Horn is located at the southernmost tip of South America, on Hornos Island in the Tierra del Fuego archipelago of southern Chile. Cape Horn is in a region with hostile waters due to the nature of the ocean between South America and Antarctica.
Cape Horn was part of a popular trade route for years, but it was notorious for devastating shipwrecks. Sailors preferred using the Panama Canal when it opened in 1914 instead of going around the volatile waters of Cape Horn. The Cape Horn area has a generally cool climate due to its southern latitude, with an average annual temperature below 50 degrees Fahrenheit.
