Boisum Pass is above 4900 m, and Chafchingol at 5150 m. The ascension is done quickly, it is better to be acclimatized. While Boisum Pass is not especially hard, Chafchingol is technical, without mentioning that you have to cross a few times a tumultuous river. Only one crossing is equipped, the others are not yet; you have water up to the bedpan, strong currents, cold, it is an experience!


Going down the Pass, two options, the rocks or the glacier, the first is very exposed but shorter, the second one is steep and under risk of avalanche. Don’t take this itinerary after August, too many risks of avalanches.  
Bakshish !

When we arrived in Koksil, we went to introduce ourselves to scouts, local police tolerating trekkers in this area. We were understanding Urdu enough to get that our team was asked to pay the local tax…Policemen were asking them 700 rps Baksheesh, just like this…they refused to pay, just mentioning that we were going to wait for the bus on the road. It seems to be common practice in the area. The best thing would be to remain at the trail level, at the bottom of the small valley, 1 hour before Koksil, and to come in the morning before 10am, to take the bus. Let your team know if they are not aware of it, and see with them.

Treks described in this rubric have all been walked by the author, itineraries are detailed daily, maps and pictures illustrate them. On no account these sheets will replace the experience of a local guide; they are complementary and should be taken as such! Never go alone, without warning anybody! The course of some trails might change from one year to another, landslides, mud slides are numerous enough.
