The geography of Nagar was very difficult mountainous terrain, which provided a certain degree of protection against invading forces. The highest mountain was the 7,788 m (25,551 ft) Mount Rakaposhi which lay to the south of the town of Nagar. As of 2009[update], the Karakoram Highway crosses Nagar, connecting Pakistan to China via the Khunjerab Pass. The road follows the Hunza river for some distance through Nagar and into the Hunza region.
