Located in the Sindh province, about 140 kilometres north of Karachi, Kirthar National Park is the first of Pakistan's parks to be included in the UN's listings in 1975. It stretches over 3087 square kilometres of rugged mountain desert.The stony valleys and rugged lines of the Kirthar hills form a haven for urial sheep, ibex and chinkara gazelle. These large mammals are hunted through this rocky terrain by jungle cats, desert cats, leopard, and desert wolf.
The park abounds with pangolin, porcupines, and monitor lizards and the large array of birdlife includes larger scavengers, such as the Griffon vulture and Egyptian vulture. 
The Fort
Apart from the abundance of wildlife, the park contains the enormous and somewhat enigmatic Rani Kot Fort. Rani Kot is the largest fort in the world, with 10 metre high sandstone ramparts stretching for a distance of 29 kilometres. From a distance, some of the walls loosely resemble the Great Wall of China as they weave through the hills. The fort was supplied water from the Rani River and a perennial spring within its walls forms pools filled with fish. Much of the area has been cultivated.
Yet there is no record for the construction of the ancient fort, nor any knowledge of it's purpose. It has been conjectured that the reason for the forts existence is its geostrategic location. Despite its extremely harsh climate, the Kirthar area occupies an important geostrategic position for two reasons. Firstly, because of its central location - between Iran and the Middle East to the west, Afghanistan and Central Asia to the north and South and South East Asia to the east. Secondly, its pretty darn close to one the great cradles of world civilisation, the Indus Valley.
Other archealogical sites of interest within the park include incredibly detailed 18th century Chaukundi style tombs at Taung and prehistoric archaeological remains at Koh Tarash.
The Controversies
Despite it's size and ecological importance, not many Pakistanis knew of the Kirthar National Park until 1991, when the local authority proposed the construction of a national highway through the park. As a result of local activism, both the profile of the park was raised and the highway was rerouted.
Shortly after the demise of the highway plans, a Shell joint venture (Premier Oil) was permitted to continue their relentless search for oil in the region by Pakistan's national government. Environmental organizations and the locals pronounced the deal illegal, citing the Sindh Wildlife Protection Ordinance of 1973, which prohibits "clearing or breaking up any land for cultivation, mining or for any other purpose in the national parks of Sindh". After a protracted legal battle and (limited) global media attention, Premier Oil withdrew their claim in September, 2001. 
The Future
Partly as a result of the court case, the Sindh Wildlife Department contracted University of Melbourne to undertake the first baseline study of the park since 1974. The goal is to inventory the Park's natural environment and human resources. When completed this data will be freely available.
When to go, and how to get there
In light of recent developments in the region, extreme caution is advised. Armed robbery and kidnapping are serious problems in many parts of rural Pakistan, particularly in the Sindh region. There have also been sectarian attacks in urban areas.
With that caveat aside, the Kirthar Park is one of the best maintained recreation parks of Pakistan. The best season to visit is from October to February. The park is greener in August, but the monsoonal weather is oppressive. Five furnished rest houses with cooking facilities and running water are situated on the edge of a wide valley in the center of the park at Karchat. They can be booked through the Sindh Wildlife Management Board, which also hires out tents. Food is available if ordered in advance, but it is better to take your own food, drink and bedding.
Rani Kot Fort lies roughly 90 kms north of Hyderabad. The route is through Kotri and the town of Sann, from where the remaining 20 kms distance is a beaten track across the scrubland, best covered by either jeep or camel. I'm told that camels can be rented from a man in Sann.
Wildlife
In 1977, 1,480 wild goat and 430 urial were counted in the park and 2,141 chinkara in the park and adjacent Surjan, Sumbak, Eri and Hothiano Game Reserve. There are now over 5,000 wild goat, about 1,250 urial and less than 150 chinkara in the park, and a further 400 wild goat and 70 urial in the game reserve . A helicopter survey conducted in November 2000 yielded estimates of the total populations of the three large indigenous ungulates in the park. The Sindh ibex population was estimated at 13,155 ± 2460, and concentrated on the Khirthar Range, with lower concentrations on Khambu and Dumbar and small numbers elsewhere; higher elevations appear critical to this species. The Sindh urial population was estimated at 10,425 ± 675 and concentrated on rocky sites with characteristic vegetation mainly near Khar and at Dumbar, with small numbers elsewhere. The chinkara population was estimated at 1060 ± 580 and concentrated in the lowlands, sharing much of its habitat with farming. The KNP populations of all three species are of conservation importance. In October 1984, 15 blackbuck from the USA were brought to Khar visitor centre for captive propagation . It is planned to introduce the species to the park.

Pakistan is home to some exotic flora and fauna in the Indian sub continent. The wildlife sanctuaries and national parks in Pakistan offer some exciting wildlife tour options. Kirthar National Park is the second largest national park in Pakistan. The park is situated in the southwest part of the Sind Province. The park is a wonderful getaway from Karachi that provides some quality time in the woods with wild animals.
The park was declared a national park in 1974 by the Sindh Wildlife Department. The Kirthar National Park is the first park in Pakistan that has been listed in the UN's list of National Parks of 1975. Though the park remains at its green best during monsoon but the best season to hit the wild trail is from October to February.
The park is home to a number of wild animals that include chinkara, leopards, Sind Ibex, gazelles, wild sheep, and other animals. The park is also home to thousands of wild goats. The other animals that you may come across in the Kirthar National Park include the rock python, Sind krait, the royal rat snake, Sind Crocodile, tortoise and the desert monitor lizard.
If you love bird watching, the park has a large number of species of birds. Some of the birds you may find in the Kirthar National Park include imperial eagle, bonnelli's eagle, golden eagle, tawny eagle, Egyptian vulture, cinereous vulture, Lagger falcon, Red-headed merlin and Eurasian griffon vulture.
