Curvas de Huanchaca

Curvas de Huanchaca: 24 switchbacks on a narrow and steep road

Curvas de Huanchaca is the name of a series of 24 hairpin turns located on the boundary of Cusco and Apurimac regions, in Peru. It’s one of the most hairpinned roads in the world.

Tucked away in the southern highlands of Peru, within the Urubamba Valley, the one-car-wide road is called Route 3SF. Cut out of the rock, it’s been recently paved and navigable by all passenger vehicles. The drive is very defiant, with 24 switchbacks on a narrow and steep road. It has no safety fences.

Set high in the Andes mountain range, this marvel of engineering is very steep, hitting a 17% of maximum gradient through some of the ramps. The most challenging section is 12.5km (7.76 miles) long. It starts crossing the Puente Huallpachaca over the Apurimac river, at 2.142m (7,027ft) above the sea level, and ends at 2.901m (9,517ft) asl. Over this distance the elevation gain is 759 meters. The average gradient is 6.07%.
