How long is Sico Pass?

Set high on an arid high plateau in the Andes mountains, the pass is 337 km (209 miles) long, running from 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).

Is Sico Pass paved?

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. In summer, the extreme temperatures are 23 degrees Celsius, and -12 in winters, prevailing cold and dry weather. The pass is open year round. Weather will be the biggest concern, with the road reaching heights of over 15,000 feet, it can get quite cold and dangerously windy.
