Abra de Chorrillos

Abra de Chorrillos, one of the highest roads of Argentina

Abra de Chorrillos (also known as Abra Alto Chorrillos) is a high mountain pass located in Salta Province, in the northwest of Argentina, at an elevation of 4.560m (14,960ft) above the sea level. It's one of the highest roads of Argentina.

The pass is traversed by the Ruta Nacional 51, a gravel and sand road, connecting the towns of Ingeniero Maury and El Alisal. The surface on this gravel road is often loose, especially along the sides of the road. It makes necessary to drive carefully and slow down whenever approaching an oncoming car. The weather on this zone is harsh and highly unpredictable. The climate is arid and cold: high temperatures vary little (since the warmer season is cloudy, and the coolest is sunny), ranging from 14°C to 21°C (57F to 70F), night temperatures go from 6°C (43F) in midsummer to -8°C (18F) in midwinter, and extremes under -15°C (5F) might be recorded. All rain falls exclusively in the summer, with values between 200 mm and 400 mm in total. Several salt flats exist in this area. This trail passes through remote areas, so you need to be prepared. The climb is simply terrible, with a notorius lack of oxygen that tests the organisms and a high degree of steepness. Most people feel altitude sickness at around 2,500-2,800 meters.
