The Great Himalayan National Park is the newest addition to India’s national parks lies within the Banjar Sub-division of the Parvati valley of Kulu division in Himachal Pradesh. The park was built in 1984. The park is spread over an area of 1,171 km that lies between an altitude of 1500 to 6000m. The Park is home to more than 375 faunal species. So far species of 31 mammals, 181 birds, 3 reptiles, 9 amphibians, 11 annelids, 17 mollusks and 127 insects belonging to six orders have been identified and documented. Most of the Himalayan fauna has been given protection under the high priority protection category of Schedule I of the Indian Wildlife (Protection) Act, 1972. The state government of Himachal Pradesh has banned hunting in the state for more than ten years. The GHNP also supports a great diversity of plant life thanks to its wide altitude range and relatively undisturbed habitats. From the lofty pinesand spruces and the great, spreading horse chestnuts of the lower valleys, to the dense cushions and prostrate branches of the alpine herbs and junipers, the Park presents an endless variety of vegetation. Although some areas have been modified by grazing, this is one of the few areas of the Western Himalayas where the forests and alpine meadows can be seen in something approaching their original state. The subalpine zone is richest in species, followed by the alpine and upper temperate zones.
A trek of 35 to 45 km in any of the Park’s valleys brings one into the high altitude habitat (3,500 m and above) of animals such as blue sheep, snow leopard, Himalayan brown bear, Himalayan thar, and musk deer. Best sightings can be made in autumn (September–November) as animals start their seasonal migration to lower altitudes. They are protected under strict guidelines of Wildlife Protection Act of 1972, hence any sort of hunting is not permitted. It also supports the variety of plant life, scattered over the park.
An eight-day trek crossing two valleys. Moderate to strenuous. Experience the transitions between two magnificent valleys. This area is Bear country; chances of sighting are very high. Good Probability of Sighting Himalayan Tahr and Musk Deer. This trek is probably the best for spotting wildlife; it takes you through the valleys of Sainj and Tirthan rivers, through a varying range of altitudes and forests, right from dense oak and chestnut to high altitude birch and rhododendron forest.
