Hunza, an independent principality for 950 years which only came under Pakistani rule in 1974, is also located in this region. The Northern Areas collectively comprise a territory of some 72,496 sq km. The Northern Areas border the Wakhan corridor of Afghanistan to the northwest, the Xinjiang territory of China to the northeast, the Indian-controlled state of Jammu and Kashmir to the southeast, the region of Pakistani-administered Azad Kashmir to the southeast and the North-West Frontier Province to the west. The main political centres are the towns of Gilgit, Skardu and Chilas.
Once, the southern route of the ancient Silk Road passed through these areas, travelled by merchants from many far-off places who stopped here and inter-married with the locals. The relatively fair-skinned and light-haired people of the area are often believed to be the descendants of the Greeks who, beginning with the soldiers of Alexander the Great, and continuing in the Greco-Buddhist period, settled in the region. The population of these areas has links to many diverse linguistic, ethnic and religious groups. Urdu is the lingua franca of the region, understood by most inhabitants. The "Shina" language is the language of 40% of the population, spoken mainly in Gilgit, throughout Diamer, and some parts of Ghizer. The "Balti" language with a similar accent, is spoken or understood by most of the population of Baltistan. Other rather localised languages include "Wakhi" spoken in upper Hunza, and some villages in Ghizer, while Khowar is the major language of Ghizer. "Burushaski" is an isolated language spoken in Hunza, Nagar, Yasin (where Khowar is also spoken), some parts of Gilgit and some villages of Punyal. Another interesting language is Domaaki, spoken by the musician clans of the region.
The region is home to some of the world's highest mountain ranges — the main ranges are the Karakoram and the western Himalayas. The Pamir mountains are to the north, and the Hindu Kush lies to the west. Five of the Eight-thousander (above 8,000m) peaks of the world are in the Northern Areas of Pakistan. Some of the world's largest glaciers outside the polar regions are also in Northern Areas, such as Baltoro Glacier, Biafo Glacier and Hispar Glacier. Amongst the highest mountains are K2 and Nanga Parbat, one of the most feared mountains in the world. The famous Karakoram Highway (KKH), the highest international road in the world, also pass through the NA to connect China with Pakistan through the Khunjrab pass, which is at an estimated altitude of 4850 meters. The pride pinnacles of the Northern Areas are:-
- K2, 2nd highest of the world at 8,611Metres
- Nanga Parbat, 9th highest of the world at 8,125 Metres
- Gasherbrum I, 11th highest of the world at 8,080 Metres
- Broad Peak, 12th highest of the world at 8,047 Metres
- Gasherbrum II-IV, 13th-17th highest of the world at 8,035 Metres - 7,932 Metres
- Masherbrum (K1), 22nd highest of the world at 7,821 Metres
- Rakaposhi, 27th highest of the world at 7,788 Metres
Deosai Plains is located above the tree line, the second highest plains of the world at 4,115 m (13,500 feet) are in the South of Skardu and in the East of the Astore Valley. The area was declared as a National Park in 1993. The Deosai Plains cover an area of almost 3,000 square kilometers. The plains remain snow-bound for good about six months from November to May.
There are more than 20,000 pieces of rock art and petroglyphs all along the Karakoram Highway in Northern Areas of Pakistan that are concentrated at ten major sites between Hunza and Shatial. The carvings were left by various invaders, traders and pilgrims who passed along the trade route, as well as by locals. The earliest date back to between 5000 and 1000 BCE, showing single animals, triangular men and hunting scenes in which the animals are larger than the hunters. These carvings were pecked into the rock with stone tools and are covered with a thick patina that proves their age.
Northern Areas Development Gateway (NADG) has been set up to enhance the access to development information related to Northern Areas of Pakistan. It is a pioneering web-based knowledge initiative presenting information on a range of issues pertaining to this region.
