Hunza Valley in Autumn

 

The Hunza is situated at an elevation of about 900 metres (3,000 ft). For many centuries, Hunza has provided the quickest access to Swat and Gandhara for a person travelling on foot. The route was impassable for pack animals; only human porters could get through, and then only with permission from the locals. Hunza was easily defended as the paths were often less than 0.5 metres (20 in) wide. The high mountain paths often crossed bare cliff faces on logs wedged into cracks in the cliff, with stones balanced on top. They were also constantly exposed to regular damage from weather and falling rocks. These were the much feared "hanging passageways" of the early travel accounts that terrified several famous Chinese Buddhist monks such as Xuanzang.
