Avalanches and heavy snowfalls can sometimes block some sections of the road and can be extremely dangerous due to frequent patches of ice. Conditions can change quickly and be harsh. Road closures can be frequent, so check conditions before traveling to this area. 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.
