Kangchenjunga was at one time regarded as the highest mountain in the world, with the aid of modern technology it is now recognised as the third highest mountain. This is an outstanding but long trek that links both the north and the south base camps in one trek. The area has for long been off the beaten trail but recently lodges have been developed to encourage more trekkers but with a very long one day journey to reach the starting point many trekkers still look to other more accessible regions. This is a real shame because the trek along the valleys and over the passes of this region provides the intrepid explorer with some of the very best of Nepalese trekking.

Kanchenjunga itself lies on the far eastern Nepal Sikkim border, a tiny Himalayan state in the north-eastern part of India. This area was closed to trekkers until the mid-1980 and today the region is protected by the Kanchenjunga Conservation Area and a special trekking permit is required. In addition to the main peak of Kangchenjunga, there are four subsidiary summits exceeding 8000m, the most important being Kangchenjunga West, also known as Yalung Kang 8505m there are also approximately twenty other peaks that exceed 7000m, the highest being Kambachen 7903m, Janu 7710m, Jongsong 7483m, Kabru ,353m, Tent Peak 7365m and the Twins 7350m.
