I am going to do ACT from 10th Sept to 1st Oct, which gives me 22 days which should be enough to cover entire trek. I am also considering to do a side trek to Tilicho lake. Initially I was worried about rain and clouds blocking the view, but I see few people even going in peak monsoon. I think weather won’t be too bad and it would be fine to do this trek in mid September, I had to plan this trek in Sept because I got some official holidays in my company which I clubbed with my vacation and got full 3 weeks for myself. I am looking forward to some trekking partners who are doing this trek in the same time frame as I am. I’m not planning to take any guide or porters. My trekking dates are fixed as I have limited number of leaves and want to enjoy most of my time in mountains.
