I was solo traveller from Australia and found NEST profile on www.meetup.com/nestadventure where I saw one of best itinerary and details so I decided to join them. It was their first meetup group so there were just me and another guy from England named Peter. We head toward Gokyo Valley with our guide Krishna and one porter named Milan. It was snowing heavily in Namche and so was Gokyo almost frozen. We were it Thagnak and almost ready to cross Chola Pass next, but unfortunately my friend Peter was about to terminate Gokyo Chola Pass Trekking because he feel serious acute mountain sickness and was airlifted to Kathmandu. My guide Krishna was busy arranging helicopter for Peter while I head toward Chola Pass with Milan. After some time Krishna appear on trail speedily to continue Gokyo Chola Pass Trekking. We descend to Dzongla and next day to Everest Base Camp our final destination of Chola Pass Trek. Even after when we were back to Kathmandu, I again do some hiking around Pokhara with my guide Krishna. I really enjoy my Gokyo Chola Pass Trekking with NEST; wish them good luck in future with large trekking group for Gokyo Chola Pass Trek.
