the world's most spectacular roads

Carretera de Chacas

Chacas road is an extreme road between Chacas and Carhuaz, with a length of 73.8km in the province of Asunción, in the Ancash Region of Peru, surrounded by the Cordillera Blanca. The dangerousity of the road (officially called Ruta departamental AN-107) makes the trip takes longer than 4 hours. The construction of the road started in 1910, finished in 1984 and in 2013 the road was asphalted.

Several buses of Transvir company cover this trip daily. The highway is not asphalted and raises by dangerous steep, but the bus drivers generally take their time. This road is one of the most spectacular in Peru taking you up to well above the snow border. During the rainy and snowy period the road may be closed.

The main risk on this curvy and narrow mountainous road which rarely permits speeds over 30km/h is coming around a blind corner and discover a vehicle proceeding toward you. Starting in Chacas (at 4.067m above sea level) you will pass the south face of Peru's highest mountain, the Huascaran (6,768 meters). The road curves endlessly down into a quiet valley and continues to Carhuaz, close to Huaraz in the Callejon de Huaylas. 


Avalanches and heavy snowfalls can sometimes block some sections of the road and can be extremely dangerous due to frequent patches of ice. The road climbs the Punta Olimpica pass, at an elevation of 4,890m above the sea level. Carhuaz is a city in the Ancash Region, located at 34 km from Huaraz, at 2,688m above sea level.


Menacing desert terrain with numerous steep, rocky climbs. Large, sharp rocks require tight maneuvering, increasing the likelihood of tire damage. High clearance, skid plates and differential lockers required. No stock vehicles. A complex network of poorly defined roads makes route-finding very difficult, even following a GPS tracklog. Very hot in summer. Carry plenty of water. Never drive this trail alone.

The construction of the Ruta departamental AN-107 started in 1910 and finished in 1984. 27 years later started the asphalt works and the new road was inaugurated in August’2013. Nowadays the whole road is asphalted, but at km. 10, there’s a short section of 2km, at an elevation of 3030m above the sea level, that remains unpaved. The road includes a section called "sector de las mil curvas" (1000 turns section) with a length of 26km and 46 hairpin turns.
