The name Cordillera Blanca in and of itself sounds imposing. Known to be one of the biggest mountain ranges in the world, the majority of its peaks measure around 6000 m.a.s.l.
Located 100 km from the Pacific coast and measuring 180 km long, The Cordillera Blanca forms a natural barrier between the coast and the Amazon jungle. Every mountain top is more beautiful than the next, and many hiking trips can be arranged through the Cordillera’s grand mountain passes. The mountain roads were built centuries ago by the native people of the region.
The Cordillera Blanca, and its many beautiful places, is now accessible by various roads using 4x4 vehicles. Huaraz, at 3091 m.a.s.l., used to be a beautiful little town until the terrible earthquake of 1970. Though the village has been reconstructed, it is not quite as beautiful as it used to be. That said, the National Park of Huascaran is close to Huaraz; founded in 1975 the Park is a nature preserve for the amazing flora and fauna of the region. The surrounding landscapes are beyond beautiful, and the area is also well-known for its giant plants called Puyas de Raymondy, some of which measure more than 10 meters. Definitely worth seeing!
