Huaraz is one of the world's premier high-altitude adventure destinations. The surrounding Cordillera Blanca offers trekking, mountaineering, ice climbing, and rock climbing at every level of experience. Beyond the peaks, the region holds pre-Inca ruins, glacial lagoons of improbable colour, and a catastrophic piece of 20th-century history at Yungay. Even those who do not set foot on a glacier will find more than enough to fill a week.
