"Hi Prem, Nice hearing you.
For me, the most memorable and challenge one are Nigutse La pass, the other after Yongma La, and Phirtse La, the last pass. There are several passes in between are also nice. Ii find most spectacle is the rock formation after descend from Nigutse La, it's really amazing and impressive. Anyway it is still a very good trip, on the scenery, landscape and others.
What to say..we missed to cross some passes due to weather but we crossed others with different scene so never know, we missed something but also gain something.
Anyway, thanks so much for organizing, I want to say food and other services support during the trek are good, and almost excellent, food (quality and quantity) are good, I would put up my testimonial on the link. I hope I can join you next trek and also want to complete the unfinished trek business"
