The Nanda Devi National Park or Valley of Flowers, established in 1982 is a national park situated around the peak of Nanda Devi (7816 m) in the state of Uttarakhand in northern India. The entire park lies at an elevation of more than 3,500 m (11,500 ft) above mean sea level.

The National Park was inscribed a World Heritage Site by UNESCO in 1988. It was later expanded and renamed as Nanda Devi and Valley of Flowers National Parks in 2005.

Within the National Park lies the Nanda Devi Sanctuary, a glacial basin surrounded by a ring of peaks between 6,000 metres (19,700 ft) and 7,500 m (24,600 ft) high, and drained by the Rishi Ganga through the Rishi Ganga Gorge, a steep almost impassable defile.

The National Park is embedded in the 2,236.74 km2 (863.61 sq mi) sized Nanda Devi Biosphere Reserve, which, in turn, is encompassed in the 5,148.57 km2 (1,987.87 sq mi)  buffer zone around the Nanda Devi and Valley of Flowers National Parks UNESCO site.

Best time to visit Nanda Devi National Park is from May to October.

Wildlife:

130 Bird and 13 Mammal Species Identified in Nanda Devi National Park

Some unique species that were once extinct are now can be seen there such as Snow leopard (Panthera uncia), Asiatic black bear (Ursus thibetanus), Himalayan brown bear (Ursus arctos), Himalayan musk deer (Moschus chrysogaster), Bharal (Pseudois nayaur) and Himalayan tahr (Hemitragus jemlahicus). The area of the reserve lies within the Western Himalayas Endemic Bird Area.

Other than the animal species, more than 400 variety of flora is also seen here. Last time, the survey was conducted in 2003, at that time only 51 types of animals were spotted there. However, this time an increase in population is not only in terms of animals and birds but also in flora as well. The team of experts were to set off in 2013 as the earlier team had visited the area in 2003. However, the study was put off after the June 2013 flood alerts in the state. Saket Badola, deputy director of Jim Corbett National Park, who led the team of experts, said that he has collected the number and will compare them with the statistics of 2003. Final comparison report of these two years will be submitted Central and state government. The reports are showing the signs of the recovery from the severe strain of unrestrained mountaineering between 1939 and 1982.
