Khunjerab Pass is the highest paved international border crossing in the world and the highest point on the Highway.
At a height of 15,397 feet, it connects Gilgit–Baltistan region of Pakistan to Xinjiang region of China.
The long, relatively flat pass is often snow-covered during the winter season and therefore is generally closed from November 30 to May 1.
At present due to formation of Atabad Lake in Hunza Region, which has blocked the Karakorum Highway near Gulmit, the pass is not road able and one has to cross the lake by boat to move further ahead into china from Pakistan.
