Khangchendzonga National Park

Khangchendzonga National Park also Kanchenjunga Biosphere Reserve is a National Park and a Biosphere reserve located in Sikkim, India. It was inscribed to the UNESCO World Heritage Sites list in July 2016, becoming the first "Mixed Heritage" site of India. The park gets its name from the mountain Kangchenjunga (alternative spelling Khangchendzonga) which is 8,586 metres (28,169 ft) tall, the third-highest peak in the world. The total area of this park is 849.5 km2 (328.0 sq mi).
The Khangchendzonga National Park (KNP) is a part of Khangchendzonga Biosphere Reserve (KBR). The KNP/KBR complex situated in North and West Sikkim districts is the biggest IBA in Sikkim, occupying nearly 40% of the State. It lies entirely along the Sikkim-Nepal border and includes the Khangchendzonga Range from the South Lhonak Glacier in trans-Himalayan Sikkim down to Barsey Rhododendron Sanctuary in the South Sikkim. This IBA stretches eastwards up to Tsungthang in North Sikkim with the Tista river flowing south from the Tso Lhamo cold desert forming its eastern boundary for most part.
The Rathong-Rangit valleys in the southern part of this IBA are a trekker’s paradise with flora from lowland subtropical forests to alpine meadows and snowcapped peaks and glaciers. This IBA has the world’s third highest (and India’s highest) peak Mt. Khangchendzonga (8,598 m) and is hence the highest altitude wildlife protected area in India. Most of the core area of this IBA is permanently snowbound with a large number of peaks which are climbers’ delights, while the peripheral areas including buffer zones and habitation are more important wildlife habitats.
