The organization of our whole trekking by our guides was excellent. There no problem which could not be solved by Kalu (guide). He never made a decision without consulting the group. In this way it was a very friendly cooperation. In our opinion, Kalu (Guide) , Sonam (Sherpa) and Tendy (helper) did a very good cooperation for the success of the trekking. Therefore we reached the summit of Mera Peak although we had very difficult conditions.
