In the southwestern part of Sikkim, in the main Himalayan range, lies the majestic Khangchendzonga or Kanchenjunga, rising to a staggering height of 8,585 m (28,169 ft) above sea level. Beside this third largest peaks, other famous mountaineering peaks in Sikkim include- Kabru, Kirat Chulior Tent Peak (7,365 m) and Sinolchu (6,887 m).
