Much of Khunjerab National Park in Gilgit-Baltistan tops 4,500m (15,000 ft) and has one of the largest concentrations of the elusive snow leopard.
As in much of Pakistan, the military is complicit in profiting from the trade in endangered species.
The Khunjerab Pass allows the international border between Pakistan and China to be crossed. At 15,397 feet above sea level, the Khunjerab Pass is the highest paved international border crossing in the world and the highest point of the dramatic Karakoram Highway, which some call an "Eighth Wonder of the World".
The pass has been used for centuries, one branch of the Silk Road. The park was established in the 1970s.
