It was a lifetime experience and a well organized Trek. The founder Naba and his climbing guides are very concerned about their guests feeling well and having an extraordinary experience. They react very flexibly to special desires and also health situations (which by nature actually happen quite often at these altitudes). The quality of their services is 99% identical to that of western trekking companies at a significantly lower cost. An important point is the 1:1 ratio between trekkers and porters. This is both fair to porters and allows maximum flexibility (e.g. leaving the group to stay behind or descending is easily possible). Thank you everyone for the wonderful experience.
