North of Lima and Huacho, one of the most scenic areas in Peru, the Callejón de Huaylas, in the department of Ancash, features many breath-taking and tough mountain mountain biking trails amongst its canyons and mountain ranges. Most circuits climb up to high altitude (3,500 meters) before dropping down steep slopes. One of the most popular routes runs from the Llanganuco Lakes (3,800 meters) to the town of Yungay. Another links the high mountain pass of Punta Olímpica (4,800 meters) with the town of Carhuaz. Both routes vary from Class A-B, and are best cycled from May to October. Cyclists should take along plenty of warm clothing and spare bicycle parts, and should take precautions regarding high altitude sickness known locally as soroche.
Overall, Cordillera Blanca is the 3rd most popular mountain bike trail of all 5 mountain biking rides in Peru.
