Paso Portachuelo Llanganuco, at an elevation of 4.767m (15.639ft) above the sea level, is perhaps the most significant gateway of the Huascaran National Park, in Peru. It’s one of the famous hairpinned roads in the world.
The road to the summit is called Carretera de Yungay (or Carretera 106). This gravel track has sheer drops on one side, and stone cliffs on the other; very sharp hair-pin turns and switchbacks. Since pre Inca times this has been the passageway straddling the continental divide. The Portachuelo Pass is located in the Yungay province (Peru) and offers a broad relatively flat corridor, between the Pacific and Atlantic watersheds.
Located within the Cordillera Blanca in the Andes of Peru, the road encompasses miles of stunning views through twisty hair pin corners, high elevations and steep grades. The breathtaking view from this point includes mounts Huascaran, Huandoy, Chopicalqui, Pisco, Chacraraju and Yanapaccha.
