Northern Traverse Trek: Sikkim

North Sikkim Trek | Whistling Arrow

18 Days | From USD 5800 pp

* Please note that the best months to plan this trip are May (for the flowers), or October*

It was during my first visit to the far north of Sikkim in 1995, that I vowed to return one day, and traverse this spectacular land of snow-capped peaks, and rhododendron covered valleys. At that time, my own plans had been scuppered by the labyrinthine local bureacracy, but now, many years later, it is now possible to get our hands on those 'special' permits ; maddening pieces of paper that, if nothing else, have at least served to hide away the awe-inspiring beauty of these glaciated amphitheatres, and virgin forested slopes, from all but the most determined of foreign trekkers.
So, starting from the fabled 'Valley of Flowers', our small team expedition will first head west, to cross a breathtaking (pun intended) high pass that lies in the southern shadows of Brumkhangse peak, before descending into one of the most beautiful rhododendron sanctuaries in the Himalayas. After relaxing in piping hot springs at the foot of the valley, we will then continue west, this time into the remotest reaches of the Kanchenjunga Biosphere Reserve; home to the indigenous tribe of Lepchas, the ancient monastery of Tholong (which for fellow plant-enthusiasts out there literally means arisaema place), and according to local legend, bon manchi - the 'man of the forest' (or yeti to you and me). And there, we'll explore our final destination; a sacred Lepcha lake that for local clans marks the 'route to heaven', a trail that zigs and zags up a big rock wall, and tops out at a stupendous pass known simply as the 'peaceful one'.
Perhaps not all good expeditions need a fitting climax, but from here, fingers crossed, the views over Kanchenjunga and the rock needles of Siniolchu, offer 'the most superb triumph of mountain architecture in the world' (in the eyes of Douglas Freshfield at least, in 1899)!
