Kangchenjunga is the third highest mountain in the world, and lies partly in Nepal and partly in Sikkim, India. It rises with an elevation of 8,586 m (28,169 ft) in a section of the Himalayas called Kangchenjunga Himal that is limited in the west by the Tamur River, in the north by the Lhonak Chu and in the east by the Teesta River.
Mount Kangchenjunga lies about 125 km (78 mi) east-south-east of Mount Everest. It is the second highest mountain of the Himalayas. Kangchenjunga Main is the highest mountain in India, and the easternmost of the mountains higher than 8,000 m (26,000 ft). It is called Five Treasures of Snow after its five high peaks, Until 1852, Kangchenjunga was assumed to be the highest mountain in the world, but calculations based on various readings and measurements made by the Great Trigonometrical Survey of India in 1849 came to the conclusion that Mount Everest, known as Peak XV at the time, was the highest. Allowing for further verification of all calculations, it was officially announced in 1856 that Kangchenjunga is the third highest mountain in the world.
Kanchenjunga-north from base camp in Nepal
There are four climbing routes to reach the summit of Kangchenjunga, three of which are in Nepal from the southwest, northwest and northeast, and one from northeastern Sikkim in India. To date, the northeastern route from Sikkim has been successfully used only three times. The Indian government has banned expeditions to Kanchenjunga, and therefore this route has been closed since 2000.
