My son and I trekked through the less-known villages, up to the base camp and camp II, and climbed the peak called Chulu West. It was our second peak climbing in Nepal and this time we tried Third Rock Adventures. They were friendly from the very first email. The travel consultant was friendly and addressed our mail promptly. The founder called us and comforted us with any doubts. The climbing team was experienced. The weather up there in the mountain synced with our itinerary and we never had to compromise anything. The acclimatization and rest day helped a lot. I highly recommend Third Rock Adventures for a climbing expedition in Nepal, they got everything up for it. Go with them.
