HUNZA-Shimshal is the highest settlement in Pakistan’s northern Hunza region and the last village before the Chinese border. It is reachable via only one rocky, hairpin turn—laden road cut into the Distegill Sar and Karun Kuh mountains. The road, known as the Shimshal Valley Road, is considered one of the world’s most dangerous. Much of it runs along the gorge of the Shimshal River, bordered by nothing but a steep drop off without guardrails. Completed in 2003 after 18 years of construction, it is an unmarked turnoff from the Karakoram Highway, navigable only by four—wheel drive.
