Hashilegen Pass, located on the Duku Highway in Xinjiang, is a key pass in the Tianshan Mountains, reaching an altitude of approximately 3,390 meters. Known for its perpetual snow and precipitous terrain, it is known as the "Glacier Pass." Its iconic Hashilegen Tunnel, once a snow corridor, is a true wonder of the highway. As a crucial thoroughfare connecting northern and southern Xinjiang, this pass is not only a geographical dividing line but also a highlight of the Duku Highway, offering magnificent snow-capped mountain scenery and a unique driving experience, allowing visitors to experience the changing seasons in a single day.
