The Khunjerab National Park is located to the extreme north of Pakistan along the border to China. It's best known for being home to snow leopards, but the huge national park (5,544 sq. km) is the natural habitat for several endangered species, like Marco Polo sheeps, brown bear, Blue sheep, Tibetan wild ass and Himalayan ibex. Due to the high elevation of 4,000 m or more, the flora is equally unique. The high altitude road crosses the Khunjerab Pass (4,693 m) before ending at the border to China, which is an attraction of itself.
