Paso de Sico

Sico Pass, a scenic border pass in the Andes

Paso de Sico is an international high mountain pass at an elevation of 4.092m (13,425ft) above the sea level, located on the border of Chile and Argentina, on an arid high plateau in the Andes mountains.

The pass is 337 km (209 miles) long and links San Pedro de Atacama, a town in El Loa Province, Antofagasta Region of northeastern Chile and San Antonio de los Cobres, a small town in Los Andes Department of the Salta Province, in northwestern Argentina. Remember this is a mountainous area, climbing up a high mountain, with a notorius absence of oxygen. Altitude and extreme weather are always a factor. In summer, the extreme temperatures are 23 degrees Celsius, and -12 in winters, prevailing cold and dry weather.

The pass is traversed by Chile Route 23, a newly paved road (in 2018) and Argentina Route 51, a challenging unpaved road. There are plans to build a new paved road in Argentina by 2022.
