Travelling Through Ruta 27 (CH-27) in the Andes
Ruta 27 is a high mountain road located in the northern part of Chile, crossing an arid plateau in the Andes mountains.
When Was Ruta 27 Built?
The road runs through a remote, semi-desert region in the Andes, with few inhabitants and an average elevation of 3,000 meters above sea level. Ruta 27 opened in 1991 and was fully paved by 2005.
Is Ruta 27 Paved?
Yes, the road is fully paved with two traffic lanes. It stretches 156 km (97 mi), connecting San Pedro de Atacama to Paso de Jama on the Argentinian border.
How Challenging Is Ruta 27?
Ruta 27 includes steep sections and challenging conditions. The region is known for strong, dry winds and intense sunlight. Drivers should bring sunglasses, plenty of water, and at least two spare tires to prepare for potential issues.
What to Expect on Ruta 27?
The road reaches its highest point at Portezuelo Paranal, a mountain pass at 4,832 meters (15,853 feet) above sea level. It is one of the highest paved roads in South America.
Drivers should exercise caution due to:
- Extreme altitude
- Limited cellphone coverage
- Long distances between petrol stations—up to 160 km (100 mi) on the Chilean side.
