A peak from the Himalayan Nanda Devi Range emerging above rain clouds
The Nanda Devi National Park or Nanda Devi Biosphere Reserve, 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.
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.
