The landscape is dominated by mountains. The park contains or is delimited by 24 peaks at least 6,000 m above the sea level. Nanda Devi is 7,816 m high.
The area is inhabited by the indigenous Bhotiya tribal community. There are 22 villages in the Niti Valley region on the periphery of the park. A majority of the villages practice trancehumance, i.e. they will live for six months in the upper villages, and move down to winter villages to avoid the extreme climate. Bhotiyas are a closely knit society and still practice their traditional customs and rituals. Village Lata is famous for its week-long Mask Dance festival observed during the second week of April every year. There are places of archaeological interest in the Niti Valley, and a 12th-century temple of Nanda Devi in the village of Lata.
The native Bhotiya community was in the forefront of Chipko Movement during the 1970s. The prompt action taken by Gaura Devi and few other village women is a milestone in the non-violent struggle of tribal communities in saving their forest wealth. The political leadership in Niti Valley Painkhanda region was provided by Comrade Govind Singh Rawat.
Wildlife in the park includes snow leopards, black and brown bears, tahrs, deer, musk deer and monkeys. Over 100 species of birds and 312 floral species have been documented.
