Sikkim. Kanchendzonga-Uttarey Trek (13d+2d)
If the Kanchendzonga Trek on its normal route seems little to you, here you have a much more important route that takes you through more isolated and wild terrain, following the edge between Nepal and Sikkim, around 4000 meters high, with impressive views of the Kanchendzonga, as of Everest, Lhotse and Makalu.
