During my research on this trek there were instances where people faced difficulty with an inexperienced guide which was my number 1 concern. Third Rock Adventures were prompt with their email and also they gave me with their phone number. I called and as we talked I became certain that I will do the Manaslu circuit trek with the company. They assured me that the trip would be as they have promised. I am glad that I did the trek with them and could not have asked more. I was least worried and enjoying the trek more. It was worth all the pain, difficulties and mild Acute Mountain Sickness. Alluring mountains, challenging trail, cultural diversity, unhampered Tibetian culture and solitary.
