It was a tough trek and I had some trouble with the altitude, but everyone suffers a little. The first few days were fun, the middle was okay, but getting up to Kala Pattar was just incredible! For sure this was the highlight of everyone's trip. Without our guide, Tanka, I am not sure that I would have made it up Kala Pattar. It's a steep last climb that's a killer and with every step I just wanted to give up. Tanka encouraged us all and without him I would have been the only one in the group not to have made it. I can't comment for all Experience the Himalaya guides, but Tanka was a great guy and a great guide. He kept the spirits high and everything ran smoothly.
