Coihaique also spelled Coyhaique in Patagonia, is the capital city of both the Coihaique Province and the Aysén Region of Chile. Founded by settlers in 1929, it is a young city. Until the twentieth century, Chile showed little interest in exploiting the remote Aisén region. The Carretera Austral road opened in the 1980s. The commune of Coihaique spans an area of 43,297 km2 (16,717 sq mi). It is surrounded by rivers (Simpson and Coihaique) and by mountains. The mountains may be snow-covered throughout the year, thus Coihaique is sometimes called the city of eternal snow. Temperatures are moderate during the months of November through April. From May until October, temperatures can be comparatively cold and accompanied by the possibility of snowfall.
